Far different is the mental training thus acquired from that gained in the same amount of time spent in mere reading. Thought is stimulated to a far greater degree. The lecture-room becomes a laboratory, where the mind of the hearer, in immediate contact with that of a man mature in the ways of study, of one whose whole life seems to have prepared him for the present hour, assimilates to itself more than knowledge. The lecturer gives what no books can give, his own force to impel his own words. His mind is ever active while he speaks. The hearer feels its workings, and his own is stirred into action by the contact. It is not given to all to enjoy the conversation and intercourse of the master-minds of the age: in the lecture-room they speak to us immediately; we feel the current of their life-blood; it pulsates through all they say. That seeming exceptions may occur, as in the case of professors who year after year deliver the same written course, can have no weight against the system. The tone and gesture, the very look, must animate the whole;--and these very written lectures, read and delivered so often, are no dead stalk, but a living stem, which puts forth new leaves and blossoms every spring. Nor is the hearer himself without his corresponding influence. His attention and eager desire for knowledge stimulate new thought in the speaker day by day, hour by hour; and many a German scholar must have felt with Friedrich August Wolf, when he says,--"I am one who has been long accustomed to the gentle charm which lies in the momentaneous unfolding of thought in the presence of attentive hearers, to that living reaction softly felt by the teacher, whereby a perennial mental harmony is awakened in his soul, which far surpasses the labors in the study, before blank walls and the feelingless paper."
