Th. Ribot, The Psychology of the Emotions (1897)
“ It is the result of a contradiction between thought and feeling, between theory and practice, between principle and tendency. Nothing is less rare, and I need scarcely adduce examples: the contrast between a man’s private and public life, between his aspect as a scientific man and his aspect as a believer. One who, in a question of scientific proof, is quite intractable, will show, in religion or in love, an unparalleled simplicity and ingenuousness. As for those who loudly profess any given doctrine, and contradict it by their actions, there is no lack of them. ”
