For the first time the personality is deliberately cultivated as such; and from that time [the European Renaissance] until today it has not been possible to separate the achievements of a civilization from the achievements of the individuals composing it. I have not the slightest doubt that this form of individuation represents a higher stage in the evolution of mankind. The future unit is the individual, a world in himself, self-contained and self-creative, freely giving and freely receiving, but essentially a free spirit.
