neither moral thinking (governed by the norms of the good and the right) nor scientific thinking (governed by the norm of truth) suffices.

  Categories of moral theory, repeatedly cited by 

stupid politicians like |Pelosi, Biden et al, 

moral theory cites  intention, blame, responsibility, character, duty, virtue, and the like do capture important aspects of the human condition, but neither moral thinking (governed by the norms of the good and the right) nor scientific thinking (governed by the norm of truth) suffices.

“Existentialism”, therefore, may be defined as the philosophical theory which holds that a further set of categories, governed by the norm of authenticity, is necessary to grasp human existence.
