Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he feels it. But from the view point of daily life – without going deeper – we exist for each other; in the first place, for those on whose smiles and welfare all our happiness depends, and next, for all those unknown to us personally, with whose destinies we are bound up by the tie of sympathy. A hundred times every day I remind myself that my inner and outer life depends on the labors of others, living and dead, and that I must exert myself in order to give in the same measure a I have received and am still receiving.
