It is much easier to give a negative than a positive answer to this question. All that we seem to have arrived at is, _Poeta nascitur non fit_; and that no amount or kind of culture can bestow the divine afflatus. Hesiod, in his “Theogony,” exhibits the Muses in the performance of their highest functions, singing choral hymns to their Heavenly Father, but gives no proper definition of poetry. Aristotle, in his treatise on “The Poetic,” does not explain its essence, but merely its principal forms. Dr. Johnson has attempted to define poetry in these words: “Poetry is the art of uniting pleasure with truth, by calling imagination to the aid of reason.” But it is well known that poetry often unites pleasure to what is not truth. According to Dr. Blair, “Poetry is the language of passion or enlivened imagination, formed most commonly into regular numbers.” This seems a pretty near approach to a true definition. Still it is defective, for there are parts of poetry which are not included either under “passion or enlivened imagination.” Competent critics will admit that a true definition seizes and exhibits the distinctive element and speciality of the thing defined; and tried by this test every definition we are acquainted with fails in doing the very thing required—determining what may be called the “differential mark” of poetry. Perhaps this question, which has so long puzzled the literary world, may be incapable of a categorical answer, but it seems to us essentially to consist of fine thoughts, deeply felt, and expressed in vivid and melodious language. Poets and poetesses see farther than other people, feel more deeply, and utter what they see and feel better. All history testifies that the poetry which has come down to us most deeply stamped with approbation, and which appears most likely to see and glorify the ages of the future, has been penetrated and inspired by moral purpose, and warmed by religious feeling. Our great kings and queens of song, are alike free from morbid weakness, moral pollution, and doubtful speculation. Such only may hope to send their names down, in thunder and in music, through the echoing aisles of the future. All lasting fame must rest on a good foundation. _BIOGRAPHY._
