Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains
in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served.
And new philosophy calls all in doubt, The element of fire is quite put out; The sun is lost, and the earth, and no man's wit Can well direct him where to look for it. And freely men confess that this world's spent, When in the planets, and the firmament They seek so many new; then see that this Is crumbled out again to his atomies. 'Tis all in pieces, all coherence gone; All just supply, and all relation: Prince, subject, Father, Son, are things forgot.
Pythagoras, Locke, Socrates - but pages might be filled up, as vainly as before, with the sad usage of all sorts of sages, who in his life-time, each was deemed a bore! The loftiest minds outrun their tardy ages.

So far as superior truth is concerned, it is enough to observe that the awakening sciences have allied themselves point by point with the philosophy of Epicurus, but point by point rejected Christianity.
A religion, that is, a true religion, must consist of ideas and facts both; not of ideas alone without facts, for then it would be mere Philosophy; - nor of facts alone without ideas, of which those facts are symbols, or out of which they arise, or upon which they are grounded: for then it would be mere History.

First know for certain what they are doing - which more than ninety per cent of the revilers are thoroughly ignorant of - and then it will explain itself in the light of the Vedantic philosophy.
