The fruits of Christianity were religious wars, butcheries, crusades, inquisitions, extermination of the natives of America, and the introduction of African slaves in their place.
The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.

You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.
