"Taking care if oneself requires knowing [connaître] oneself."
"But if you take proper care of yourself, that is, you know ontologically what you are, if you know what you are capable of, if you know what it means for you to be a citizen of a city, to be the master of a household in an oikos, if you know what things you should and should not fear, if you know what you can reasonably hope for and, on the other hand, what things should not matter to you, if you know, finally, that you should not be afraid of death - if you know all this, you cannot abuse your power over others. Thus, there is no danger."
(Michel Foucault, The Ethics of the Concern of the Self as a Practice of Freedom)
