[120] We need scarcely remark, in this connection, that every unhappy experience awakens the craving for assistance and consolation, and therefore indirectly gives rise to an effort to create sympathy. This point must, however, be passed over when treating of impulsive, purely emotional manifestations. As to the pleasures and consolations of mutual sympathy, compare, moreover, Smith, Theory of Moral Sentiments, pp. 10-13, especially p. 12.
