Science knows no boundaries, and efforts to create barriers – whether to keep new ideas within or to prevent new ones from entering from the outside – have universally proved harmful to progress.
--
in a tribute to Andrei Sakharov, Address at the National Academy of Science, November 13, 1988Sidney Drell
The ever-present impulse is to push against restriction and, in so doing, to feel intolerably hemmed in. Thus in practice, every liberation increases the sense of oppression. Nor is the paradox merely in the mind: the laws enacted to secure the rights of every person and group, by creating protective boundaries, create new barriers.
Jacques Barzun
The progress of science, of good science, depends on novel ideas and on intellectual freedom: science has very often been advanced by outsiders (remember that Bohr and Einstein regarded themselves as outsiders).
Paul Karl Feyerabend
The bullying powers use different excuses to prevent transfer of science and technology and progress of the nations of our region.
Mahmoud Ahmadinejad
The philosophy of anarchism is included in the word "Liberty"; yet it is comprehensive enough to include all things else that are conducive to progress. No barriers whatever to human progression, to thought, or investigation are placed by anarchism; nothing is considered so true or so certain, that future discoveries may not prove it false; therefore, it has but one infallible, unchangeable motto, "Freedom." Freedom to discover any truth, freedom to develop, to live naturally and fully. Other schools of thought are composed of crystallized ideas — principles that are caught and impaled between the planks of long platforms, and considered too sacred to be disturbed by a close investigation. In all other "issues" there is always a limit; some imaginary boundary line beyond which the searching mind dare not penetrate, lest some pet idea melt into a myth. But anarchism is the usher of science — the master of ceremonies to all forms of truth. It would remove all barriers between the human being and natural development.
Lucy Parsons
The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.
