It is always a great challenge to balance conflicting tensions when a predominant tendency manifests itself in the spirit, either compelling externalization or internalization. The personality often reveals this difficulty, the main problem of which is not to follow or move away from the innate tendency, but to deal with the opposite, which often presents itself as a duty. A duty, then, to act against one’s nature, to continually do the most painful thing, under constant threat of condemnation by one’s conscience! Perhaps this is the greatest usefulness of biographies: to record the sprouts of this conflict in the lives of those for whom living is opposed to doing work.
