I have, in the present collection, omitted the poem[2] from which the volume published in 1852 took its title. I have done so, not because the subject of it was a Sicilian Greek born between two and three thousand years ago, although many persons would think this a sufficient reason. Neither have I done so because I had, in my own opinion, failed in the delineation which I intended to effect. I intended to delineate the feelings of one of the last of the Greek religious philosophers, one of the family of Orpheus and Musæus, having survived his fellows, living on into a time when the habits of Greek thought and feeling had begun fast to change, character to dwindle, the influence of the Sophists[3] to prevail. Into the feelings of a man so situated there are entered much that we are accustomed to consider as exclusively modern; how much, the fragments of Empedocles himself which remain to us are sufficient at least to indicate. What those who are familiar only with the great monuments of early Greek genius suppose to be its exclusive characteristics, have disappeared; the calm, the cheerfulness, the disinterested objectivity have disappeared; the dialogue of the mind with itself has commenced; modern problems have presented themselves; we hear already the doubts, we witness the discouragement, of Hamlet and of Faust. The representation of such a man's feelings must be interesting, if consistently drawn. We all naturally take pleasure, says Aristotle,[4] in any imitation or representation whatever: this is the basis of our love of poetry: and we take pleasure in them, he adds, because all knowledge is naturally agreeable to us; not to the philosopher only, but to mankind at large. Every representation therefore which is consistently drawn may be supposed to be interesting, inasmuch as it gratifies this natural interest in knowledge of all kinds. What is _not_ interesting, is that which does not add to our knowledge of any kind; that which is vaguely conceived and loosely drawn; a representation which is general, indeterminate, and faint, instead of being particular, precise, and firm. Any accurate representation may therefore be expected to be interesting; but, if the representation be a poetical one, more than this is demanded. It is demanded, not only that it shall interest, but also that it shall inspirit and rejoice the reader: that it shall convey a charm, and infuse delight. For the Muses, as Hesiod[5] says, were born that they might be "a forgetfulness of evils, and a truce from cares": and it is not enough that the poet should add to the knowledge of men, it is required of him also that he should add to their happiness. "All art," says Schiller, "is dedicated to joy, and there is no higher and no more serious problem, than how to make men happy. The right art is that alone, which creates the highest enjoyment."
