There are several methods of studying the sciences. Amongst a multitude of men you will find a selfish, mercantile, and trading taste for the discoveries of the mind, which must not be confounded with that disinterested passion which is kindled in the heart of the few.

Context

“This opinion of the public influences the judgment of the men who cultivate the sciences; they are persuaded that they may succeed in those pursuits without meditation, or deterred from such pursuits as demand it.
There are several methods of studying the sciences. Amongst a multitude of men you will find a selfish, mercantile, and trading taste for the discoveries of the mind, which must not be confounded with that disinterested passion which is kindled in the heart of the few. A desire to utilize knowledge is one thing; the pure desire to know is another. I do not doubt that in a few minds and far between, an ardent, inexhaustible love of truth springs up, self-supported, and living in ceaseless fruition without ever attaining the satisfaction which it seeks.” source
