6 Friedrich Hayek Quotes on Truth

Friedrich Hayek quotes on truth

87. Personally, I find that the most objectionable feature of the conservative attitude is its propensity to reject well-substantiated new knowledge because it dislikes some of the consequences which seem to follow from it - or, to put it bluntly, its obscurantism. I will not deny that scientists as much as others are given to fads and fashions and that we have much reason to be cautious in accepting the conclusions that they draw from their latest theories. But the reasons for our reluctance must themselves be rational and must be kept separate from our regret that the new theories upset our cherished beliefs. I can have little patience with those who oppose, for instance, the theory of evolution or what are called 'mechanistic' explanations of the phenomena of life because of certain moral consequences which at first seem to follow from these theories, and still less with those who regard it as irrelevant or impious to ask certain questions at all. By refusing to face the facts, the conservative only weakens his own position. Frequently the conclusions which rationalist presumption draws from new scientific insights do not at all follow from them. But only by actively taking part in the elaboration of the consequences of new discoveries do we learn whether or not they fit into our world picture and, if so, how. Should our moral beliefs really prove to be dependent on factual assumptions shown to be incorrect, it would hardly be moral to defend them by refusing to acknowledge facts.

106. There may thus well exist better 'scientific' evidence for a false theory, which will be accepted because it is more 'scientific', than for a valid explanation, which is rejected because there is no sufficient quantitative evidence for it.

109. I confess that I prefer true but imperfect knowledge, even if it leaves much indetermined and unpredictable, to a pretence of exact knowledge that is likely to be false. The credit which the apparent conformity with recognized scientific standards can gain for seemingly simple but false theories may, as the present instance shows, have grave consequences.

113. The conflict between what in its present mood the public expects science to achieve in satisfaction of popular hopes and what is really in its power is a serious matter because, even if the true scientists should all recognize the limitations of what they can do in the field of human affairs, so long as the public expects more there will always be some who will pretend, and perhaps honestly believe, that they can do more to meet popular demands than is really in their power. It is often difficult enough for the expert, and certainly in many instances impossible for the layman, to distinguish between legitimate and illegitimate claims advanced in the name of science.

121. There are two ways of looking at the pattern of human activities which lead to very different conclusions concerning both its explanation and the possibilities of deliberately altering it. Of these one is based on conceptions which are demonstrably false, yet are so pleasing to human vanity that they have gained great influence and are constantly employed even by people who know that they rest on a fiction, but believe that fiction to be innocuous. The other, although few people will question its basic contentions if they are stated abstractly, leads in some respects to conclusions so unwelcome that few are willing to follow through to the end. The first gives us a sense of unlimited power to realize our wishes, while the second leads to the insight that there are limitations to what we can deliberately bring about, and to the recognition that some of our present hopes are delusions. Yet the effect of allowing ourselves to be deluded by the first view has always been that man has actually limited the scope of what he can achieve. For it has always been the recognition of the limits of the possible which has enabled man to make full use of his powers.

153. Should our moral beliefs really prove to be dependent on factual assumptions shown to be incorrect, it would be hardly moral to defend them by refusing to acknowledge the facts.
