Philosophy is a goddess, whose head indeed is in heaven, but whose feet are upon earth; she attempts more than she accomplishes, and promises more than she performs.

Falsehood, like a drawing in perspective, will not bear to be examined in every point of view, because it is a good imitation of truth, as a perspective is of the reality, only in one. But truth, like that reality of which the perspective is the representation, will bear to be scrutinized in all points of view, and though examined under every situation, is one and the same.
