"I desire to see the world and the whirligig of humanity, which constitute, so to speak, a living book, a second course of education.” “Yes, there is no harm in looking at other corners of the world besides one’s own.” “You speak truly. There is no harm in such a proceeding. Thereby one may see things which one has not before encountered, one may meet men with whom one has not before come in contact." (N. Gogol "Dead souls")
