We veer from plan to plan. None of our wishes is free, none is unqualified, none is lasting. But, whatever the ultimate explanation might be for the power and pervasiveness of inconsistency in human life, Seneca stands firm on his recommendation. Before all else. That is a strong phrase.
Inconsistency is falsehood.
An interesting concept. When you act consistently you are true to yourself. An inconsistent act is falsely related to your deepest goals and values, and, as such, will not have any positive lasting value. Seneca sees consistency as central to making each of us singular, whole, integrated people. You present yourself to the world as being other than who you are.
