“What is wanted is not the will to believe, but the will to find out, which is the exact opposite.”

“Most men think that in framing their political opinions they are actuated by desire for the public good; but 9 times out of 10 a man’s politics can be predicted from the way in which he makes a living. This has led some people to maintain, and many more to believe practically, that in such matters it is impossible to be objective, and that no method is possible except a tug-of-war between classes with opposite bias.”

“What we firmly believe, if it is true, is called knowledge, provided it is either intuitive or inferred (logically or psychologically) from intuitive knowledge from which it follows logically. What we firmly believe, if it is not true, is called error. What we firmly believe, if it is neither knowledge nor error, and also what we believe hesitatingly, because it is, or is derived from, something which has not the highest degree of self-evidence, may be called probable opinion. Thus the greater part of what would commonly pass as knowledge is more or less probable opinion.”

“The extent to which beliefs are based upon evidence is very much less than believers suppose. Take the kind of action which is most nearly rational: the investment of money by a rich City man. You will often find that his view (say) on the question whether the French franc will go up or down depends upon his political sympathies, and yet is so strongly held that he is prepared to risk money on it.”

“One of the causes of unhappiness among intellectuals in the present day is that so many of them, especially those whose skill is literary, find no opportunity for the independent exercise of their talents, but have to hire themselves out to rich corporations directed by Philistines, who insist upon their producing what they themselves regard as pernicious nonsense. If you were to inquire among journalists in either England or America whether they believed in the policy of the newspaper for which they worked, you would find, I believe, that only a small minority do so; the rest, for the sake of a livelihood, prostitute their skill to purposes which they believe to be harmful. Such work cannot bring any real satisfaction, and in the course of reconciling himself to the doing of it, a man has to make himself so cynical that he can no longer derive whole-hearted satisfaction from anything whatever. I cannot condemn men who undertake work of this sort, since starvation is too serious an alternative, but I think that where it is possible to do work that is satisfactory to man’s constructive impulses without entirely starving, he will be well advised from the point of view of his own happiness if he chooses it in preference to work much more highly paid but not seeming to him worth doing on its own account. Without self-respect genuine happiness is scarcely possible. And the man who is ashamed of his work can hardly achieve self-respect.”

“Never let yourself be diverted, either by what you wish to believe, or what you think could have beneficent social effects if it were believed; but look only and solely at what are the facts.”

“Politicians do not find any attractions in a view which does not lend itself to party declamation, and ordinary mortals prefer views which attribute misfortune to the machinations of their enemies.”
