Ideology and Principles

If I am not mistaken this fashionable contempt for “ideology,” or for all general principles or “isms,” is a characteristic attitude of the disillusioned socialists who, because they have been forced by the inherent contradictions of their own ideology to discard it, have concluded that all ideologies must be erroneous and that in order to be rational one must do without one.

– F.A Hayek

Certainty and Reliability

A good scientist is never ‘certain’. Lack of certainty is precisely what makes conclusions more reliable than the conclusions of those who are certain: because the good scientist will be ready to shift to a different point of view if better elements of evidence, or novel arguments emerge. Therefore certainty is not only something of no use, but is in fact damaging, if we value reliability.

– Carlo Rovelli
