A Quote by Peter Medawar
I cannot give any scientist of any age better advice than this: the intensity of a conviction that a hypothesis is true has no bearing over whether it is true or not.

The intensity of a conviction that a hypothesis is true has no bearing on whether it is true or false. The importance of the strength of our conviction is only to provide a proportionately strong incentive to find out if the hypothesis will stand up to critical evaluation.
Mr. Darwin's hypothesis is not, so far as I am aware, inconsistent with any known biological fact; on the contrary, if admitted, the facts of Development, of Comparative Anatomy, of Geographical Distribution, and of Palaeontology, become connected together, and exhibit a meaning such as they never possessed before; and I, for one, am fully convinced that if not precisely true, that hypothesis is as near an approximation to the truth as, for example, the Copernican hypothesis was to the true theory of the planetary motions.
Current organisms have a higher probability of sharing a single code if the common ancestry hypothesis is true than they'd have if the hypothesis of separate ancestry were true. That is, the simpler hypothesis has the higher likelihood in the technical sense of "likelihood" used in statistics.
What is more true than anything else? To swim is true and to sink is true. One cannot speak any more of being, one must speak onlyof the mess.
"True science has no belief," says Dr. Fenwick, in Bulwer-Lytton's 'Strange Story;' "true science knows but three states of mind: denial, conviction, and the vast interval between the two, which is not belief, but the suspension of judgment." Such, perhaps, was true science in Dr. Fenwick's days. But the true science of our modern times proceeds otherwise; it either denies point-blank, without any preliminary investigation, or sits in the interim, between denial and conviction, and, dictionary in hand, invents new Graeco-Latin appellations for non-existing kinds of hysteria!
If you find yourself loving any pleasure more than your prayers, any book better than the Bible, any house better than the house of the Lord, any table better than the Lord's table, any persons better than Christ, or any indulgence better than the hope of heaven – be alarmed.
[Coining phrase "null hypothesis"] In relation to any experiment we may speak of this hypothesis as the "null hypothesis," and it should be noted that the null hypothesis is never proved or established, but is possibly disproved, in the course of experimentation. Every experiment may be said to exist only in order to give the facts a chance of disproving the null hypothesis.
The conduct of a man, who studies philosophy in this careless manner, is more truly sceptical than that of any one, who feeling inhimself an inclination to it, is yet so over-whelm'd with doubts and scruples, as totally to reject it. A true sceptic will be diffident of his philosophical doubts, as well as of his philosophical conviction; and will never refuse any innocent satisfaction, which offers itself, upon account of either of them.
Are your desires purely selfish? Do your tastes run to a grand home, automobiles, fine clothes, an abundance of amusements, and so forth? If so, look around you at people who have such things in superabundance. Are they any happier, do you think, than you are? Are they any better morally? Are they any stronger physically? Are they better liked by their friends than you are by your friends? ... Carnegie said, Millionaires rarely smile. This is substantially true.
Experience keeps a dear school, but fools will learn in no other, and scarce in that; for it is true we may give advice, but we cannot give conduct.
It is true that the present is powerfully shaped by the past. But it is also true that ... insight at any age keeps us from singing the same sad songs again.
I do not go to the gym. I do not train. I am not that careful about what I eat. I cannot give you any advice about keeping fit. The best advice I can give is choose your parents wisely.
The true office of any faith is to give life a meaning which death cannot destroy.
True love, like any other strong and addicting drug, is boring — once the tale of encounter and discovery is told, kisses quickly grow stale and caresses tiresome… except, of course, to those who share the kisses, who give and take the caresses while every sound and color of the world seems to deepen and brighten around them. As with any other strong drug, true first love is really only interesting to those who have become its prisoners. And, as is true of any other strong and addicting drug, true first love is dangerous.
He had only one vanity; he thought he could give advice better than any other person.
A true poem is distinguished not so much by a felicitous expression, or any thought it suggests, as by the atmosphere which surrounds it. Most have beauty of outline merely, and are striking as the form and bearing of a stranger; but true verses come toward us indistinctly, as the very breath of all friendliness, and envelop us in their spirit and fragrance.
