A Quote by Peter Medawar
For a scientist must indeed be freely imaginative and yet skeptical, creative and yet a critic. There is a sense in which he must be free, but another in which his thought must be very preceisely regimented; there is poetry in science, but also a lot of bookkeeping.

There are roads which must not be followed, armies which must not be attacked, towns which must not be besieged, positions which must not be contested, commands of the sovereign which must not be obeyed.
[T]rue socialism must be voluntary - not coerced. Even in the most complete system of society we can conceive the individual must still have rights and property. He must appropriate food to sustain his life. He must wear clothes which are his. He must have his private and exclusive apartment, and must have the right to be in some place on God's earth from which he cannot be evicted by landlord of society.
There must be no barriers to freedom of inquiry... There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. Our political life is also predicated on openness. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress.
There is a crucial distinction to be made between innovation and originality. The second, unlike the first, can never break with what preceded it: to be original, an artist must also belong to the tradition from which he departs. To put it another way, he must violate the expectations of his audience, but he must also, in countless ways, uphold and endorse them.
Not only in order to act morally, but even to formulate theoretical questions, devise experiments, choose which ones to perform and what conclusions to draw from then - we must presuppose that we are free. That's the sense in which it is true that for Kant "we must assume we are free."
Man must be able to think freely and he must be able to express his thoughts freely! He who is against this is not only fascist and primitive but at the same time is a very great coward also! Only the brave and the honourable men are never afraid of freedom of thought and freedom of expression of ideas! Just like the cockroaches do not like the light, evil minds also do not like the freedom of thoughts!
The Judo pupil, therefore, must cultivate his mind; he must never feel fear, never lose his temper, never be off his guard; but he must be cool and calm, though not absent-minded; he must act as quick as thought, according to circumstances. He must also be dexterous as well as bold both in attack and in defense.
It is unwise to equate scientific activity with what we call reason, poetic activity with what we call imagination. Without the imaginative leap from facts to generalisation, no theoretic discovery in science is made. The poet, on the other hand, must not imagine but reason--that is to say, he must exercise a great deal of consciously directed thought in the selection and rejection of his data: there is a technical logic, a poetic reasoning in his choice of the words, rhythms and images by which a poem's coherence is achieved.
In order to appreciate a great man, we must know his surroundings. We must understand the scope of the drama in which he played - the part he acted - and we must also know his audience.

Is evolution a theory, a system, or a hypothesis? It is much more it is a general postulate to which all theories, all hypotheses, all systems must henceforward bow and which they must satisfy in order to be thinkable and true. Evolution is a light which illuminates all facts, a trajectory which all lines of thought must follow this is what evolution is.
Another of the qualities of science is that it teaches the value of rational thought, as well as the importance of freedom of thought; the positive results that come from doubting that all the lessons are true... Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.
The genius of poetry must work out its own salvation in a man; it cannot be matured by law and precept, but by sensation and watchfulness in itself. That which is creative must create itself.
Reason must approach nature with the view, indeed, of receiving information from it, not, however, in the character of a pupil, who listens to all that his master chooses to tell him, but in that of a judge, who compels the witnesses to reply to those questions which he himself thinks fit to propose. To this single idea must the revolution be ascribed, by which, after groping in the dark for so many centuries, natural science was at length conducted into the path of certain progress.
The critic, to interpret his artist, even to understand his artist, must be able to get into the mind of his artist; he must feel and comprehend the vast pressure of the creative passion.
