The sciences, even the best,-mathematics and astronomy,-are like sportsmen, who seize whatever prey offers, even without being able to make any use of it.
Let us even bid our dearest friends farewell, and defy them, saying, "Who are you? Unhand me: I will be dependent no more." Ah! seest thou not, O brother, that thus we part only to meet again on a higher platform, and only be more each other's, because we are more our own?
With each divine impulse the mind rends the thin rinds of the visible and finite, and comes out into eternity, and inspires and expires its air. It converses with truths that have always been spoken in the world, and becomes conscious of a closer sympathy with Zeno and Arrian, than with persons in the house.
Men of sense esteem wealth to be the assimilation of nature to themselves, the converting of the sap and juices of the planet to the incarnation and nutriment of their design.
Yet things are knowable! They are knowable, because, being from one, things correspond. There is a scale: and the correspondence of heaven to earth, of matter to mind, of the part to the whole, is our guide. As there is a science of stars, called astronomy; and science of quantities, called mathematics; a science of qualities, called chemistry; so there is a science of sciences,--I call it Dialectic,--which is the Intellect discriminating the false and the true.
In my utter impotence to test the authenticity of the report of my senses, to know whether the impressions they make on me correspond with outlying objects, what difference does it make, whether Orion is up there in heaven, or some god paints the image in the firmament of the soul?
I am old, yet I look at wise men and see that I am very young. I look over those stars yonder, and into the myriads of the aspirant and ordered souls, and see I am a stranger and a youth and have yet my spurs to win. Too ridiculous are these airs of age.
So all that is said of the wise man by Stoic or Oriental or modern essayist, describes to each reader his own idea, describes his unattained but attainable self.
