He is a great average man；one who, to the best thinking, adds a proportion and equality in his faculties, so that men see in him their own dreams and glimpses made available and made to pass for what they are. A great common-sense is his warrant and qualification to be the world’s interpreter. He has reason, as all the philosophic and poetic class have: but he has also what they have not, – this strong solving sense to reconcile his poetry with the appearances of the world, and build a bridge from the streets of cities to the Atlantis. He omits never this graduation, but slopes his thought, however picturesque the precipice on one side, to an access from the plain. He never writes in ecstasy, or catches us up into poetic raptures.
Plato apprehended the cardinal facts. He could prostrate himself on the earth and cover his eyes whilst he adorned that which cannot be numbered, or gauged, or known, or named: that of which every thing can be affirmed and denied: that “which is entity and nonentity.” He called it super-essential. He even stood ready, as in the Parmenides, to demonstrate that it was so, – that this Being exceeded the limits of intellect. No man ever more fully acknowledged the Ineffable. Having paid his homage, as for the human race, to the Illimitable, he then stood erect, and for the human race affirmed, “And yet things are knowable!” – that is, the Asia in his mind was first heartily honored, – the ocean of love and power, before form, before will, before knowledge, the Same, the Good, the One; and now, refreshed and empowered by this worship, the instinct of Europe, namely, culture, returns; and he cries, “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; a 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. It rests on the observation of identity and diversity; for to judge is to unite to an object the notion which belongs to it. 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. Dialectic must teach the use of them. “This is of that rank that no intellectual man will enter on any study for its own sake, but only with a view to advance himself in that one sole science which embraces all.”
“The essence or peculiarity of man is to comprehend a whole; or that which in the diversity of sensations can be comprised under a rational unity.” “The soul which has never perceived the truth, cannot pass into the human form.” I announce to men the Intellect. I announce the good of being interpenetrated by the mind that made nature: this benefit, namely, that it can understand nature, which it made and maketh. Nature is good, but intellect is better: as the law-giver is before the law-receiver. I give you joy, O sons of men! that truth is altogether wholesome; that we have hope to search out what might be the very self of everything. The misery of man is to be baulked of the sight of essence and to be stuffed with conjecture; but the supreme good is reality; the supreme beauty is reality; and all virtue and all felicity depend on this science of the real: for courage is nothing else than knowledge; the fairest fortune that can befall man, is to be guided by his d?mon to that which is truly his own. This also is the essence of justice, – to attend every one his own: nay, the notion of virtue is not to be arrived at except through direct contemplation of the divine essence. Courage then! for “the persuasion that we must search that which we do not know, will render us, beyond comparison, better, braver and more industrious than if we thought it impossible to discover what we do not know, and useless to search for it.” He secures a position not to be commanded, by his passion for reality; valuing philosophy only as it is the pleasure of conversing with real being.
