Rationalism and sentimentalism

"This decline has not come about all at once; one can follow its stages throughout modern philosophy. It is the loss or the forgetting of true intellectuality that has made possible two errors which, though seemingly opposed, are in reality correlative and complementary: rationalism and sentimentalism. From the moment all purely intellectual knowledge came to be denied or ignored...the logical end was positivism and agnosticism, with the attendant 'scientistic' aberrations on the one hand, and on the other all those contemporary theories which, not content with what reason can produce, set out after something else, but do so in the direction of sentiment and instinct, that is, beneath reason, and not above it..." 

Rene Guenon, "Symbols of Sacred Science"
