So that in reading or hearing of another, a man shall seem unto himself
To be recollecting images or arguments, native and congenial to his mind:
And yet, what shall we say,—who can arede the riddle?
The brain may be clockwork, and mind its spring, mechanism quickened by a spirit.
Who so shrewd as rightly to divide life, instinct, reason;
Trees, zoophytes, creatures of the plain, and savage men among them?
Hath the mimosa instinct,—or the scallop more than life,—
Or the dog less than reason,—or the brute-man more than instinct?
What is the cause of health,—and the gendering of disease?
Why should arsenic kill, and whence is the potency of antidotes?
