Do you wonder how one mind can have such vivid consciousness of the feelings of another, while their characters are cast in such different moulds? It is, indeed, wonderful--but the power is that of sympathy and genius. The dramatic poet, whose heart breathes love to all living things, and whose overflowing tenderness diffuses itself over the beauty even of unliving nature, may yet paint with his creative hand the steeled heart of him who sits on a throne of blood--the lust of crime in a mind polluted with wickedness--the remorse of acts which could never pass in thought through his imagination as his own. For, in the act of imagination he can suppress in his mind its own peculiar feelings--its good and gracious affections--call up from their hidden places those elements of our being, of which the seeds were sown in him as in all--give them unnatural magnitude and power--conceive the disorder of passions, the perpetration of crimes, the tortures of remorse, or the scorn of that human weakness, from which his own gentle bosom and blameless life are pure and free. He can bring himself, in short, into an imaginary and momentary sympathy with the wicked, just as his mind falls of itself into a natural and true sympathy with those whose character is accordant with his own; and watching the emotions and workings of his mind in the spontaneous and in the forced sympathy, he knows and understands for himself what passes in the minds of others. What is done in the highest degree by the highest genius, is done by all of ourselves in lesser degree, and unconsciously, at every moment in our intercourse with one another. To this kind of sympathy, so essential to our knowledge of the human mind, and without which there can be neither poetry nor philosophy, are necessary a largeness of heart which willingly yields itself to conceive the feelings and states of others whose character is utterly unlike its own, and freedom from any inordinate overpowering passion which quenches in the mind the feelings of nature it has already known, and places it in habitual enmity to the affections and happiness of its kind. To paint bad passions is not to praise them; they alone can paint them well who hate, fear, or pity them; and therefore Baillie has done so--nay start not--better than Byron.
