A Quote by Bertrand Russell

A habit of basing convictions upon evidence, and of giving to them only that degree or certainty which the evidence warrants, would, if it became general, cure most of the ills from which the world suffers.
Where do we say that a cell became a blade of grass, which became a starfish, which became a cat, which became a donkey, which became a human being? There's a real lack of evidence from change from actual species to a different type of species.
That general warrants, whereby an officer or messenger may be commanded to search suspected places without evidence of a fact committed, or to seize any person or persons not named, or whose offence is not particularly described and supported by evidence, are grievous and oppressive, and ought not to be granted.
Whether we like it or not, quantification in history is here to stay for reasons which the quantifiers themselves might not actively approve. We are becoming a numerate society: almost instinctively there seems now to be a greater degree of truth in evidence expressed numerically than in any literary evidence, no matter how shaky the statistical evidence, or acute the observing eye.
In 1995, we had evidence of the brother-in-law of Osama bin Laden being in the Philippines, living in the Philippines. We had evidence of front organizations set up in the Philippines. And we uncovered evidence about, which would help the U.S. with - about the perpetuators of the World Trade Center bombing.
I destroy because for me everything that proceeds from reason is untrustworthy. I believe only in the evidence of what stirs my marrow, not in the evidence of what addresses itself to my reason. I have found levels in the realm of the nerve. I now feel capable of evaluating the evidence. There is for me an evidence in the realm of pure flesh which has nothing to do with the evidence of reason. The eternal conflict between reason and the heart is decided in my very flesh, but in my flesh irrigated by nerves.
There is evidence for the deity of Jesus -- good, strong, historical , cumulative evidence; evidence to which an honest person can subscribe without committing intellectual suicide.
No democratic delusion is more fatuous than that which holds that all men are capable of reason, and hence susceptible to conversion by evidence. If religions depended upon evidence for their prolongation, then all of them would collapse.
It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty. This is what Agnosticism asserts; and, in my opinion, it is all that is essential to Agnosticism. That which Agnostics deny and repudiate, as immoral, is the contrary doctrine, that there are propositions which men ought to believe without logically satisfactory evidence; and that reprobation ought to attach to the profession of disbelief in such inadequately supported propositions.
Most scientists never look at UFO evidence, which leads to their conclusion that there is no evidence.
If an opinion contrary to your own makes you angry, that is a sign that you are subsciously aware of having no good reason for thinking as you do. [...] The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find, on examination, that your belief is going beyond what the evidence warrants.
Convictions following the admission into evidence of confessions which are involuntary, i.e., the product of coercion, either physical or psychological, cannot stand. This is so not because such confessions are unlikely to be true but because the methods used to extract them offend an underlying principle in the enforcement of our criminal law: that ours is an accusatorial, and not an inquisitorial, system - a system in which the State must establish guilt by evidence independently and freely secured, and may not, by coercion, prove its charges against an accused out of his own mouth.
Such evidence is not the only kind which produces belief; though positivism maintains that it is the only kind which ought to produce so high a degree of confidence as all minds have or can be made to have through their agreements.
And, if we have any evidence that the wisdom which formed the plan is in the man, we have the very same evidence, that the power which executed it is in him also.
I can UNDERSTAND pessimism, but I don't BELIEVE in it. It's not simply a matter of faith, but of historical EVIDENCE. Not overwhelming evidence, just enough to give HOPE, because for hope we don't need certainty, only POSSIBILITY.
We may define "faith" as the firm belief in something for which there is no evidence. Where there is evidence, no one speaks of "faith." We do not speak of faith that two and two are four or that the earth is round. We only speak of faith when we wish to substitute emotion for evidence. The substitution of emotion for evidence is apt to lead to strife, since different groups, substitute different emotions.
It was while I was studying philosophy that I came to understand. . . that it is no sign of moral or spiritual strength to believe that for which one has no evidence, neither a priori evidence as in math, nor a posteriori evidence as in science. . . . It's a violation almost immoral in its transgressiveness to shirk the responsibilities of rationality.
