"However, the voice of the rationalist is a sound social reaction, it is an act of self-defense by society against the dangers of being dominated by uncontrollable forces such as a saint proclaiming a revelation or a madman affirming the products of his sick imagination, and finally a fraud who wants to convert others to his views for the sake of his egoistic and unworthy purposes. It is better to rely on the safe but modest nourishment of reason than, in fear of missing the voice of ‘Truth’, to let oneself be fed with all sorts of uncontrollable nourishment which may more often be poisonous than healthy and beneficial."

“All through these attempts to give the traditional concept of God a more explicit content philosophers did not mind if, in making the content more explicit, they departed from the original, highly emotionally charged, concept of deity.”

“What then is the content of the concept of God common to all monotheistic religions? What remains, it seems, is only the emotional content: the highest enthusiasm and respect, humility and submissiveness”

“If he takes an empiricist position in regard to the source of knowledge and a realist one in regard to the limits of knowledge, he will see no need or even possibility of seeking a world-view other than that provided by science as based on experience. If he inclines towards an aprioristic position, or even more, if he is convinced by the arguments of irrationalists, he will seek his world-view in an aprioristic way, or he will appeal to intuition or mystical experience”

“The fundamental thesis of ordinary, represented for instance by Poincare, states that there are problems which cannot be solved by appeal to experience unless one introduces a certain convention, since only such a convention, together with experimental data, makes it possible to solve the problem in question. The judgements which combine to make up such a solution are thus not forced on us by empirical data alone, but their adoption depends partly on our recognition, since the said convention which co-determines the solution of the problem can be arbitrarily changed by us so that as a result we obtain different judgements.”

“By spreading logical culture, we prepare the foundation for a scientific world-view and by doing this we enable development.”

“According to Husserl, that 'act of meaning', or the use of a given phrase as an expression of a certain language, consists in the fact that a sensory content appears in consciousness, by means of which one might think visually about that phrase, should that content be joined by an appropriate intention directed to that phrase. But when a given phrase is used as an expression belonging to a certain language, then that sensory content is joined by another intention, not necessarily a representative one, which is however in principle directed to something other than that phrase itself. Together with the sensory content in question, that intention makes up a uniform experience, but neither the experiencing of that sensory content, nor that intention is a complete, independent experience. Both the one and the other are non-independent parts of the experience as a whole. The meaning of a given expression would be, according to Husserl, the type under which that intention joined to the sensory content must fall if the given phrase is to be used as an expression belonging precisely to that language”
