Scientific reasoning is a dialogue between the possible and the actual, between proposal and disposal between what might be true, and what is in fact the case.

More quotes by Peter Medawar

Observation is the generative act in scientific discovery. For all its aberrations, the evidence of the senses is essentially to be relied upon provided we observe nature as a child does, without prejudices and preconceptions, but with that clear and candid vision which adults lose and scientists must strive to regain.
Peter Medawar
Image
No scientist is admired for failing in the attempt to solve problems that lie beyond his competence. ... Good scientists study the most important problems they think they can solve. It is, after all, their professional business to solve problems, not merely to grapple with them.
Peter Medawar
Image
In no sense other than an utterly trivial one is reproduction the inverse of chemical disintegration. It is a misunderstanding of genetics to suppose that reproduction is only 'intended' to make facsimiles, for parasexual processes of genetical exchange are to be found in the simplest living things.
Peter Medawar
Image
Scientists who think science consists of unprejudiced data-gathering without speculation are merely cows grazing on the pasture of knowledge.
Peter Medawar
Image
Psychoanalytic theory is the most stupendous intellectual confidence trick of the twentieth century and a terminal product as well-something akin to a dinosaur or zeppelin in the history of ideas, a vast structure of radically unsound design and with no posterity.

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.

An experiment not worth doing is not worth doing well.

Heredity proposes and development disposes.

Is the Scientific Paper a Fraud?

The case I shall find evidence for is that when literature arrives, it expels science.
Peter Medawar
Image
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.
Peter Medawar
Image
I reckon that for all the use it has been to science about four-fifths of my time has been wasted, and I believe this to be the common lot of people who are not merely playing follow-my-leader in research.
Peter Medawar
Image
The art of research [is] the art of making difficult problems soluble by devising means of getting at them.
Peter Medawar
Image
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.
Peter Medawar
Image
[A certain class of explanations in science are] analgesics that dull the ache of incomprehension without removing the cause.
Peter Medawar
Image
The fact that scientists do not consciously practice a formal methodology is very poor evidence that no such methodology exists. It could be said-has been said-that there is a distinctive methodology of science which scientists practice unwittingly, like the chap in Moliere who found that all his life, unknowingly, he had been speaking prose.

I do not propose to criticize the fatuous argument I have just outlined here, to expound is to expose.
Peter Medawar
Image
Twice in my life I have spent two weary and scientifically profitless years seeking evidence to corroborate dearly loved hypotheses that later proved to be groundless times such as these are hard for scientists-days of leaden gray skies bringing with them a miserable sense of oppression and inadequacy.

A danger sign that fellow-obsessionals will at once recognize is the tendency to regard the happiest moments of your life as those that occur when someone who has an appointment to see you is prevented from coming.
Peter Medawar
Image
To abdicate from the rule of reason and substitute for it an authentication of belief by the intentness and degree of conviction with which we hold it can be perilous and destructive. Religious beliefs give a spurious spiritual dimension to tribal enmities.
