Summary

author:Victor Hugo Letters on American Slavery — Letter from M. Passy (1860)

Humanity is governed by laws which continually impel it to extend, without ceasing, the sphere of its knowledge. There is no discovery which does not conduct it to new discoveries; each generation adds its own to the mass which it has received from the past, and thus from age to age are the strength and riches of civilization augmented.
