Whenever philosophers have determined to separate systematic knowledge from moral virtue and pretended that knowledge should stand on its own feet as self-sufficient, the result has been disastrous. Knowledge, like a human body from which the blood is removed and replaced by, say, the blood of a goat, has languished and perished at the reckless hands of those who subjected it to such treatment. It is in fact easier to create a living, intelligent being by chemically tossing together physical components than to create philosophy without love of truth and virtue.
