Peter Medawar
Sir Peter Brian Medawar OM CBE FRS was a British biologist born in Brazil, whose work on graft rejection and the discovery of acquired immune tolerance was fundamental to the practice of tissue and organ transplants. For his works in immunology he is regarded as the "father of transplantation". He is remembered for his wit in real life and popular writings.

I do not believe indeed, I deem it a comic blunder to believe that the exercise of reason is sufficient to explain our condition and where necessary to remedy it, but I do believe that the exercise of reason is at all times necessary...
To deride the hope of progress is the ultimate fatuity, the last word in poverty of spirit and meanness of mind.
If a scientist were to cut his ear off, no one would take it as evidence of a heightened sensibility.
When asked to make the formal declaration that I did not intend to overthrow the Constitution of the United States, I was fool enough to reply that I had no such purpose, but that were I to do it by mistake I should be inexpressibly contrite.
The purpose of scientific enquiry is not to compile an inventory of factual information, nor to build up a totalitarian world picture of natural Laws in which every event that is not compulsory is forbidden. We should think of it rather as a logically articulated structure of justifiable beliefs about nature.
The USA is so enormous, and so numerous are its schools, colleges and religious seminaries, many devoted to special religious beliefs ranging from the unorthodox to the dotty, that we can hardly wonder at its yielding a more bounteous harvest of gobbledygook than the rest of the world put together.
The art of research [is] the art of making difficult problems soluble by devising means of getting at them.
Any scientist of any age who wants to make important discoveries must study important problems. Dull or piffling problems yield dull or piffling answers. It is not not enough that a problem should be "interesting." ... The problem must be such that it matters what the answer is-whether to science generally or to mankind.
It goes with the passionate intensity and deep conviction of the truth of a religious belief, and of course of the importance of the superstitious observances that go with it, that we should want others to share it - and the only certain way to cause a religious belief to be held by everyone is to liquidate nonbelievers. The price in blood and tears that mankind generally has had to pay for the comfort and spiritual refreshment that religion has brought to a few has been too great to justify our entrusting moral accountancy to religious belief.
The bells which toll for mankind are—most of them, anyway—like the bells of Alpine cattle; they are attached to our own necks, and it must be our fault if they do not make a cheerful and harmonious sound.
The alternative to thinking in evolutionary terms is not to think at all.
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.
Scientific reasoning is a kind of dialogue between the possible and the actual, between what might be and what is in fact the case.
