Why should we injure our health by close study? The exalted pleasure which intellectual pursuits afford would scarcely be equivalent to the hours of languor that follow; especially, if it be necessary to take into the reckoning the doubts and disappointments that cloud our researches. Vanity and vexation close every inquiry: for the cause which we particularly wished to discover flies like the horizon before us as we advance. The ignorant, on the contrary, resemble children, and suppose, that if they could walk straight forward they should at last arrive where the earth and clouds meet. Yet, disappointed as we are in our researches, the mind gains strength by the exercise, sufficient, perhaps, to comprehend the answers which, in another step of existence, it may receive to the anxious questions it asked, when the understanding with feeble wing was fluttering round the visible effects to dive into the hidden cause.

The passions also, the winds of life, would be useless, if not injurious, did the substance which composes our thinking being, after we have thought in vain, only become the support of vegetable life, and invigorate a cabbage, or blush in a rose. The appetites would answer every earthly purpose, and produce more moderate and permanent happiness. But the powers of the soul that are of little use here, and, probably, disturb our animal enjoyments, even while conscious dignity makes us glory in possessing them, prove that life is merely an education, a state of infancy, to which the only hopes worth cherishing should not be sacrificed. I mean, therefore, to infer, that we ought to have a precise idea of what we wish to attain by education, for the immortality of the soul is contradicted by the actions of many people who firmly profess the belief.
