[Alyosha] was to some extent a youth of our last epoch — that is, honest in nature, desiring the truth, seeking for it and believing in it, and seeking to serve it at once with all the strength of his soul, seeking for immediate action, and ready to sacrifice everything, life itself, for it. Though these young men unhappily fail to understand that the sacrifice of life is, in many cases, the easiest of all sacrifices, and that to sacrifice, for instance, five or six years of their seething youth to hard and tedious study, if only to multiply tenfold their powers of serving the truth and the cause they have set before them as their goal, such a sacrifice is utterly beyond the strength of many of them.
