The correct scale for adjusting the hierarchy of intelligences is furnished by the degree in which the mind takes merely individual or approaches universal views of things. The brute recognizes only the individual as such: its comprehension does not extend beyond the limits of the individual. But man reduces the individual to the general; herein lies the exercise of his reason; and the higher his intelligence reaches, the nearer do his general ideas approach the point at which they become universal.
The works of fine art, poetry and philosophy produced by a nation are the outcome of the superfluous intellect existing in it.
Arthur Schopenhauer
