the means given to us by nature. And finally, Posidonius said that it was to live engaged in contemplating the truth and order of the universe, and forming himself as he best can, in nothing influenced by the irrational part of his soul. And some of the later Stoics defined the great end to consist in living agreeably to the constitution of man. Why should I mention Aristo? He said that the end was indifference; but what is indifferent simply abandons the indifferent. Shall I bring forward the opinions of Herillus? Herillus states the end to be to live according to science.

Further, Lycus the Peripatetic used to say that the final end was the true joy of the soul; as Leucimus, that it was the joy it had in what was good, Critolaus, also a Peripatetic, said that it was the perfection of a life flowing rightly according to nature, referring to the perfection accomplished by the three kinds according to tradition.
We must, however, not rest satisfied with these, but endeavour as we best can to adduce the doctrines laid down on the point by the naturalists; for they say that Anaxagoras of Clazomenæ affirmed contemplation and the freedom flowing from it to be the end of life; Heraclitus the Ephesian, complacency. The Pontic Heraclides relates, that Pythagoras taught that the knowledge of the perfection of the numbers[1] was happiness of the soul. The Abderites also teach the existence of an end. Democritus, in his work On the Chief End, said it was cheerfulness, which he also called well-being, and often exclaims, "For delight and its absence are the boundary of those who have reached full age;" Hecatæus, that it was sufficiency to one's self; Apollodotus of Cyzicum, that it was delectation; as Nausiphanes, that it was undauntedness,[2] for he said that it was this that
