How often have men of observation profited by the remembrance of words which, at the time they heard them, they did not "_perfectly understand!_" We never study any thing of which we imagine our knowledge to be perfect.

To learn, and, to understand, are, with respect to any science or art, one and the same thing.

With respect to difficult or unintelligible phraseology alone, are they different.

He who by study has once stored his memory with the sound and appropriate language of any important doctrine, can never, without some folly or conceit akin to madness, repent of the acquisition.

Milton, in his academy, professed to teach things rather than words; and many others have made plausible profession of the same thing since.
