The word praxis (πρᾶξις) in ancient Greek referred to activity engaged in by free men.

The philosopher Aristotle held that there were three basic activities of man:

  • theoria (thinking),
  • poiesis (making),
  • and praxis (doing).

Corresponding to these activities were three types of knowledge:

  • theoretical, the end goal being truth;
  • poietical, the end goal being production;
  • and practical, the end goal being action.

Aristotle further divided the knowledge derived from praxis into

  • ethics,
  • economics
  • and politics.

Aristotle distinguished between eupraxia (εὐπραξία, “good praxis”) and dyspraxia (δυσπραξία, “bad praxis, misfortune”).

Happiness in life includes self sufficiency with a family, friends and community.

All living things have nutrition and growth as work, which includes perceiving.

According to Aristotle, articulate speech (logos), including both being open to persuasion by reasoning, and thinking things through is more particularly human.

Human happiness will involve reason and it will be over a lifetime

“The Good of man is the active exercise of his soul’s faculties in conformity with excellence or virtue, or if there be several human excellences or virtues, in conformity with the best and most perfect among them. Moreover, to be happy takes a complete lifetime; for one swallow does not make a spring.”
