11The GNU Manifesto
12*****************
13
14 The GNU Manifesto which appears below was written by Richard
15 Stallman at the beginning of the GNU project, to ask for
16 participation and support. For the first few years, it was
17 updated in minor ways to account for developments, but now it
18 seems best to leave it unchanged as most people have seen it.
19
20 Since that time, we have learned about certain common
21 misunderstandings that different wording could help avoid.
22 Footnotes added in 1993 help clarify these points.

28What's GNU? Gnu's Not Unix!
29============================
30
31 GNU, which stands for Gnu's Not Unix, is the name for the complete
32Unix-compatible software system which I am writing so that I can give it
33away free to everyone who can use it.(1) Several other volunteers are
34helping me. Contributions of time, money, programs and equipment are
35greatly needed.
36
37 So far we have an Emacs text editor with Lisp for writing editor
38commands, a source level debugger, a yacc-compatible parser generator,
39a linker, and around 35 utilities. A shell (command interpreter) is
40nearly completed. A new portable optimizing C compiler has compiled
41itself and may be released this year. An initial kernel exists but
42many more features are needed to emulate Unix. When the kernel and
43compiler are finished, it will be possible to distribute a GNU system
44suitable for program development. We will use TeX as our text
45formatter, but an nroff is being worked on. We will use the free,
46portable X window system as well. After this we will add a portable
47Common Lisp, an Empire game, a spreadsheet, and hundreds of other
48things, plus on-line documentation. We hope to supply, eventually,
49everything useful that normally comes with a Unix system, and more.
50
51 GNU will be able to run Unix programs, but will not be identical to
52Unix. We will make all improvements that are convenient, based on our
53experience with other operating systems. In particular, we plan to
54have longer file names, file version numbers, a crashproof file system,
55file name completion perhaps, terminal-independent display support, and
56perhaps eventually a Lisp-based window system through which several
57Lisp programs and ordinary Unix programs can share a screen. Both C
58and Lisp will be available as system programming languages. We will
59try to support UUCP, MIT Chaosnet, and Internet protocols for
60communication.
61
62 GNU is aimed initially at machines in the 68000/16000 class with
63virtual memory, because they are the easiest machines to make it run
64on. The extra effort to make it run on smaller machines will be left
65to someone who wants to use it on them.
66
67 To avoid horrible confusion, please pronounce the `G' in the word
68`GNU' when it is the name of this project.
69
70Why I Must Write GNU
71====================
72
73 I consider that the golden rule requires that if I like a program I
74must share it with other people who like it. Software sellers want to
75divide the users and conquer them, making each user agree not to share
76with others. I refuse to break solidarity with other users in this
77way. I cannot in good conscience sign a nondisclosure agreement or a
78software license agreement. For years I worked within the Artificial
79Intelligence Lab to resist such tendencies and other inhospitalities,
80but eventually they had gone too far: I could not remain in an
81institution where such things are done for me against my will.
82
83 So that I can continue to use computers without dishonor, I have
84decided to put together a sufficient body of free software so that I
85will be able to get along without any software that is not free. I
86have resigned from the AI lab to deny MIT any legal excuse to prevent
87me from giving GNU away.
88
89Why GNU Will Be Compatible with Unix
90====================================
91
92 Unix is not my ideal system, but it is not too bad. The essential
93features of Unix seem to be good ones, and I think I can fill in what
94Unix lacks without spoiling them. And a system compatible with Unix
95would be convenient for many other people to adopt.
96
97How GNU Will Be Available
98=========================
99
100 GNU is not in the public domain. Everyone will be permitted to
101modify and redistribute GNU, but no distributor will be allowed to
102restrict its further redistribution. That is to say, proprietary
103modifications will not be allowed. I want to make sure that all
104versions of GNU remain free.
105
106Why Many Other Programmers Want to Help
107=======================================
108
109 I have found many other programmers who are excited about GNU and
110want to help.
111
112 Many programmers are unhappy about the commercialization of system
113software. It may enable them to make more money, but it requires them
114to feel in conflict with other programmers in general rather than feel
115as comrades. The fundamental act of friendship among programmers is the
116sharing of programs; marketing arrangements now typically used
117essentially forbid programmers to treat others as friends. The
118purchaser of software must choose between friendship and obeying the
119law. Naturally, many decide that friendship is more important. But
120those who believe in law often do not feel at ease with either choice.
121They become cynical and think that programming is just a way of making
122money.
123
124 By working on and using GNU rather than proprietary programs, we can
125be hospitable to everyone and obey the law. In addition, GNU serves as
126an example to inspire and a banner to rally others to join us in
127sharing. This can give us a feeling of harmony which is impossible if
128we use software that is not free. For about half the programmers I
129talk to, this is an important happiness that money cannot replace.
130
131How You Can Contribute
132======================
133
134 I am asking computer manufacturers for donations of machines and
135money. I'm asking individuals for donations of programs and work.
136
137 One consequence you can expect if you donate machines is that GNU
138will run on them at an early date. The machines should be complete,
139ready to use systems, approved for use in a residential area, and not
140in need of sophisticated cooling or power.
141
142 I have found very many programmers eager to contribute part-time
143work for GNU. For most projects, such part-time distributed work would
144be very hard to coordinate; the independently-written parts would not
145work together. But for the particular task of replacing Unix, this
146problem is absent. A complete Unix system contains hundreds of utility
147programs, each of which is documented separately. Most interface
148specifications are fixed by Unix compatibility. If each contributor
149can write a compatible replacement for a single Unix utility, and make
150it work properly in place of the original on a Unix system, then these
151utilities will work right when put together. Even allowing for Murphy
152to create a few unexpected problems, assembling these components will
153be a feasible task. (The kernel will require closer communication and
154will be worked on by a small, tight group.)
155
156 If I get donations of money, I may be able to hire a few people full
157or part time. The salary won't be high by programmers' standards, but
158I'm looking for people for whom building community spirit is as
159important as making money. I view this as a way of enabling dedicated
160people to devote their full energies to working on GNU by sparing them
161the need to make a living in another way.
162
163Why All Computer Users Will Benefit
164===================================
165
166 Once GNU is written, everyone will be able to obtain good system
167software free, just like air.(2)
168
169 This means much more than just saving everyone the price of a Unix
170license. It means that much wasteful duplication of system programming
171effort will be avoided. This effort can go instead into advancing the
172state of the art.
173
174 Complete system sources will be available to everyone. As a result,
175a user who needs changes in the system will always be free to make them
176himself, or hire any available programmer or company to make them for
177him. Users will no longer be at the mercy of one programmer or company
178which owns the sources and is in sole position to make changes.
179
180 Schools will be able to provide a much more educational environment
181by encouraging all students to study and improve the system code.
182Harvard's computer lab used to have the policy that no program could be
183installed on the system if its sources were not on public display, and
184upheld it by actually refusing to install certain programs. I was very
185much inspired by this.
186
187 Finally, the overhead of considering who owns the system software
188and what one is or is not entitled to do with it will be lifted.
189
190 Arrangements to make people pay for using a program, including
191licensing of copies, always incur a tremendous cost to society through
192the cumbersome mechanisms necessary to figure out how much (that is,
193which programs) a person must pay for. And only a police state can
194force everyone to obey them. Consider a space station where air must
195be manufactured at great cost: charging each breather per liter of air
196may be fair, but wearing the metered gas mask all day and all night is
197intolerable even if everyone can afford to pay the air bill. And the
198TV cameras everywhere to see if you ever take the mask off are
199outrageous. It's better to support the air plant with a head tax and
200chuck the masks.
201
202 Copying all or parts of a program is as natural to a programmer as
203breathing, and as productive. It ought to be as free.
204
205Some Easily Rebutted Objections to GNU's Goals
206==============================================
207
208 "Nobody will use it if it is free, because that means they can't
209 rely on any support."
210
211 "You have to charge for the program to pay for providing the
212 support."
213
214 If people would rather pay for GNU plus service than get GNU free
215without service, a company to provide just service to people who have
216obtained GNU free ought to be profitable.(3)
217
218 We must distinguish between support in the form of real programming
219work and mere handholding. The former is something one cannot rely on
220from a software vendor. If your problem is not shared by enough
221people, the vendor will tell you to get lost.
222
223 If your business needs to be able to rely on support, the only way
224is to have all the necessary sources and tools. Then you can hire any
225available person to fix your problem; you are not at the mercy of any
226individual. With Unix, the price of sources puts this out of
227consideration for most businesses. With GNU this will be easy. It is
228still possible for there to be no available competent person, but this
229problem cannot be blamed on distribution arrangements. GNU does not
230eliminate all the world's problems, only some of them.
231
232 Meanwhile, the users who know nothing about computers need
233handholding: doing things for them which they could easily do
234themselves but don't know how.
235
236 Such services could be provided by companies that sell just
237hand-holding and repair service. If it is true that users would rather
238spend money and get a product with service, they will also be willing
239to buy the service having got the product free. The service companies
240will compete in quality and price; users will not be tied to any
241particular one. Meanwhile, those of us who don't need the service
242should be able to use the program without paying for the service.
243
244 "You cannot reach many people without advertising, and you must
245 charge for the program to support that."
246
247 "It's no use advertising a program people can get free."
248
249 There are various forms of free or very cheap publicity that can be
250used to inform numbers of computer users about something like GNU. But
251it may be true that one can reach more microcomputer users with
252advertising. If this is really so, a business which advertises the
253service of copying and mailing GNU for a fee ought to be successful
254enough to pay for its advertising and more. This way, only the users
255who benefit from the advertising pay for it.
256
257 On the other hand, if many people get GNU from their friends, and
258such companies don't succeed, this will show that advertising was not
259really necessary to spread GNU. Why is it that free market advocates
260don't want to let the free market decide this?(4)
261
262 "My company needs a proprietary operating system to get a
263 competitive edge."
264
265 GNU will remove operating system software from the realm of
266competition. You will not be able to get an edge in this area, but
267neither will your competitors be able to get an edge over you. You and
268they will compete in other areas, while benefiting mutually in this
269one. If your business is selling an operating system, you will not
270like GNU, but that's tough on you. If your business is something else,
271GNU can save you from being pushed into the expensive business of
272selling operating systems.
273
274 I would like to see GNU development supported by gifts from many
275manufacturers and users, reducing the cost to each.(5)
276
277 "Don't programmers deserve a reward for their creativity?"
278
279 If anything deserves a reward, it is social contribution.
280Creativity can be a social contribution, but only in so far as society
281is free to use the results. If programmers deserve to be rewarded for
282creating innovative programs, by the same token they deserve to be
283punished if they restrict the use of these programs.
284
285 "Shouldn't a programmer be able to ask for a reward for his
286 creativity?"
287
288 There is nothing wrong with wanting pay for work, or seeking to
289maximize one's income, as long as one does not use means that are
290destructive. But the means customary in the field of software today
291are based on destruction.
292
293 Extracting money from users of a program by restricting their use of
294it is destructive because the restrictions reduce the amount and the
295ways that the program can be used. This reduces the amount of wealth
296that humanity derives from the program. When there is a deliberate
297choice to restrict, the harmful consequences are deliberate destruction.
298
299 The reason a good citizen does not use such destructive means to
300become wealthier is that, if everyone did so, we would all become
301poorer from the mutual destructiveness. This is Kantian ethics; or,
302the Golden Rule. Since I do not like the consequences that result if
303everyone hoards information, I am required to consider it wrong for one
304to do so. Specifically, the desire to be rewarded for one's creativity
305does not justify depriving the world in general of all or part of that
306creativity.
307
308 "Won't programmers starve?"
309
310 I could answer that nobody is forced to be a programmer. Most of us
311cannot manage to get any money for standing on the street and making
312faces. But we are not, as a result, condemned to spend our lives
313standing on the street making faces, and starving. We do something
314else.
315
316 But that is the wrong answer because it accepts the questioner's
317implicit assumption: that without ownership of software, programmers
318cannot possibly be paid a cent. Supposedly it is all or nothing.
319
320 The real reason programmers will not starve is that it will still be
321possible for them to get paid for programming; just not paid as much as
322now.
323
324 Restricting copying is not the only basis for business in software.
325It is the most common basis because it brings in the most money. If it
326were prohibited, or rejected by the customer, software business would
327move to other bases of organization which are now used less often.
328There are always numerous ways to organize any kind of business.
329
330 Probably programming will not be as lucrative on the new basis as it
331is now. But that is not an argument against the change. It is not
332considered an injustice that sales clerks make the salaries that they
333now do. If programmers made the same, that would not be an injustice
334either. (In practice they would still make considerably more than
335that.)
336
337 "Don't people have a right to control how their creativity is
338 used?"
339
340 "Control over the use of one's ideas" really constitutes control over
341other people's lives; and it is usually used to make their lives more
342difficult.
343
6b61353c 344 People who have studied the issue of intellectual property rights(6)
1bac2ebb
DL
345carefully (such as lawyers) say that there is no intrinsic right to
346intellectual property. The kinds of supposed intellectual property
347rights that the government recognizes were created by specific acts of
348legislation for specific purposes.
349
350 For example, the patent system was established to encourage
351inventors to disclose the details of their inventions. Its purpose was
352to help society rather than to help inventors. At the time, the life
353span of 17 years for a patent was short compared with the rate of
354advance of the state of the art. Since patents are an issue only among
355manufacturers, for whom the cost and effort of a license agreement are
356small compared with setting up production, the patents often do not do
357much harm. They do not obstruct most individuals who use patented
358products.
359
360 The idea of copyright did not exist in ancient times, when authors
361frequently copied other authors at length in works of non-fiction. This
362practice was useful, and is the only way many authors' works have
363survived even in part. The copyright system was created expressly for
364the purpose of encouraging authorship. In the domain for which it was
365invented--books, which could be copied economically only on a printing
366press--it did little harm, and did not obstruct most of the individuals
367who read the books.
368
369 All intellectual property rights are just licenses granted by society
370because it was thought, rightly or wrongly, that society as a whole
371would benefit by granting them. But in any particular situation, we
372have to ask: are we really better off granting such license? What kind
373of act are we licensing a person to do?
374
375 The case of programs today is very different from that of books a
376hundred years ago. The fact that the easiest way to copy a program is
377from one neighbor to another, the fact that a program has both source
378code and object code which are distinct, and the fact that a program is
379used rather than read and enjoyed, combine to create a situation in
380which a person who enforces a copyright is harming society as a whole
381both materially and spiritually; in which a person should not do so
382regardless of whether the law enables him to.
383
384 "Competition makes things get done better."
385
386 The paradigm of competition is a race: by rewarding the winner, we
387encourage everyone to run faster. When capitalism really works this
388way, it does a good job; but its defenders are wrong in assuming it
389always works this way. If the runners forget why the reward is offered
390and become intent on winning, no matter how, they may find other
391strategies--such as, attacking other runners. If the runners get into
392a fist fight, they will all finish late.
393
394 Proprietary and secret software is the moral equivalent of runners
395in a fist fight. Sad to say, the only referee we've got does not seem
396to object to fights; he just regulates them ("For every ten yards you
397run, you can fire one shot"). He really ought to break them up, and
398penalize runners for even trying to fight.
399
400 "Won't everyone stop programming without a monetary incentive?"
401
402 Actually, many people will program with absolutely no monetary
403incentive. Programming has an irresistible fascination for some
404people, usually the people who are best at it. There is no shortage of
405professional musicians who keep at it even though they have no hope of
406making a living that way.
407
408 But really this question, though commonly asked, is not appropriate
409to the situation. Pay for programmers will not disappear, only become
410less. So the right question is, will anyone program with a reduced
411monetary incentive? My experience shows that they will.
412
413 For more than ten years, many of the world's best programmers worked
414at the Artificial Intelligence Lab for far less money than they could
415have had anywhere else. They got many kinds of non-monetary rewards:
416fame and appreciation, for example. And creativity is also fun, a
417reward in itself.
418
419 Then most of them left when offered a chance to do the same
420interesting work for a lot of money.
421
422 What the facts show is that people will program for reasons other
423than riches; but if given a chance to make a lot of money as well, they
424will come to expect and demand it. Low-paying organizations do poorly
425in competition with high-paying ones, but they do not have to do badly
426if the high-paying ones are banned.
427
428 "We need the programmers desperately. If they demand that we stop
429 helping our neighbors, we have to obey."
430
431 You're never so desperate that you have to obey this sort of demand.
432Remember: millions for defense, but not a cent for tribute!
433
434 "Programmers need to make a living somehow."
435
436 In the short run, this is true. However, there are plenty of ways
437that programmers could make a living without selling the right to use a
438program. This way is customary now because it brings programmers and
439businessmen the most money, not because it is the only way to make a
440living. It is easy to find other ways if you want to find them. Here
441are a number of examples.
442
443 A manufacturer introducing a new computer will pay for the porting of
444operating systems onto the new hardware.
445
446 The sale of teaching, hand-holding and maintenance services could
447also employ programmers.
448
449 People with new ideas could distribute programs as freeware, asking
450for donations from satisfied users, or selling hand-holding services.
451I have met people who are already working this way successfully.
452
453 Users with related needs can form users' groups, and pay dues. A
454group would contract with programming companies to write programs that
455the group's members would like to use.
456
457 All sorts of development can be funded with a Software Tax:
458
459 Suppose everyone who buys a computer has to pay x percent of the
460 price as a software tax. The government gives this to an agency
461 like the NSF to spend on software development.
462
463 But if the computer buyer makes a donation to software development
464 himself, he can take a credit against the tax. He can donate to
465 the project of his own choosing--often, chosen because he hopes to
466 use the results when it is done. He can take a credit for any
467 amount of donation up to the total tax he had to pay.
468
469 The total tax rate could be decided by a vote of the payers of the
470 tax, weighted according to the amount they will be taxed on.
471
472 The consequences:
473
474 * The computer-using community supports software development.
475
476 * This community decides what level of support is needed.
477
478 * Users who care which projects their share is spent on can
479 choose this for themselves.
480
481 In the long run, making programs free is a step toward the
482post-scarcity world, where nobody will have to work very hard just to
483make a living. People will be free to devote themselves to activities
484that are fun, such as programming, after spending the necessary ten
485hours a week on required tasks such as legislation, family counseling,
486robot repair and asteroid prospecting. There will be no need to be
487able to make a living from programming.
488
489 We have already greatly reduced the amount of work that the whole
490society must do for its actual productivity, but only a little of this
491has translated itself into leisure for workers because much
492nonproductive activity is required to accompany productive activity.
493The main causes of this are bureaucracy and isometric struggles against
494competition. Free software will greatly reduce these drains in the
495area of software production. We must do this, in order for technical
496gains in productivity to translate into less work for us.
497
498 ---------- Footnotes ----------
499
500 (1) The wording here was careless. The intention was that nobody
501would have to pay for *permission* to use the GNU system. But the
502words don't make this clear, and people often interpret them as saying
503that copies of GNU should always be distributed at little or no charge.
504That was never the intent; later on, the manifesto mentions the
505possibility of companies providing the service of distribution for a
506profit. Subsequently I have learned to distinguish carefully between
507"free" in the sense of freedom and "free" in the sense of price. Free
508software is software that users have the freedom to distribute and
509change. Some users may obtain copies at no charge, while others pay to
510obtain copies--and if the funds help support improving the software, so
511much the better. The important thing is that everyone who has a copy
512has the freedom to cooperate with others in using it.
513
514 (2) This is another place I failed to distinguish carefully between
515the two different meanings of "free". The statement as it stands is
516not false--you can get copies of GNU software at no charge, from your
517friends or over the net. But it does suggest the wrong idea.
518
519 (3) Several such companies now exist.
520
521 (4) The Free Software Foundation raises most of its funds from a
522distribution service, although it is a charity rather than a company.
523If *no one* chooses to obtain copies by ordering from the FSF, it
524will be unable to do its work. But this does not mean that proprietary

535biased; more subtle is the fact that it lumps together various

538lead others to suppose this is one coherent issue. The way to be
539clear is to to discuss patents, copyrights, and trademarks separately.
