“I, who said forty years ago that we should have had Socialism already but for the Socialists, am quite willing to drop the name if dropping it will help me to get the thing.”

Context: It is far more likely that by the time nationalization has become the rule, and private enterprise the exception, Socialism (which is really rather a bad name for the business) will be spoken of, if at all, as a crazy religion held by a fanatical sect in that darkest of dark ages, the nineteenth century. Already, indeed, I am told that Socialism has had its day, and that the sooner we stop talking nonsense about it and set to work, like the practical people we are, to nationalize the coal mines and complete a national electrification scheme, the better. And I, who said forty years ago that we should have had Socialism already but for the Socialists, am quite willing to drop the name if dropping it will help me to get the thing. What I meant by my jibe at the Socialists of the eighteen-eighties was that nothing is ever done, and much is prevented, by people who do not realize that they cannot do everything at once.

“While free software by any other name would give you the same freedom, it makes a big difference which name we use: different words convey different ideas.”

1990s, Why "Free Software" is better than "Open Source" (1998)
Context: While free software by any other name would give you the same freedom, it makes a big difference which name we use: different words convey different ideas.
In 1998, some of the people in the free software community began using the term "open source software" instead of "free software" to describe what they do. The term "open source" quickly became associated with a different approach, a different philosophy, different values, and even a different criterion for which licenses are acceptable. The Free Software movement and the Open Source movement are today separate movements with different views and goals, although we can and do work together on some practical projects.
The fundamental difference between the two movements is in their values, their ways of looking at the world. For the Open Source movement, the issue of whether software should be open source is a practical question, not an ethical one. As one person put it, "Open source is a development methodology; free software is a social movement." For the Open Source movement, non-free software is a suboptimal solution. For the Free Software movement, non-free software is a social problem and free software is the solution.
