"The studious class are their own victims; they are thin and pale, their feet are cold, their heads are hot, the night is without sleep, the day a fear of interruption,—pallor, squalor, hunger, and egotism. If you come near them and see what conceits they entertain—they are abstractionists, and spend their days and nights in dreaming some dream; in expecting the homage of society to some precious scheme built on a truth, but destitute of proportion in its presentment, of justness in its application, and of all energy of will in the schemer to embody and vitalize it."
