IS Cicero, Tusculan Disputations, 3, 6: "Truly, philosophy is the medicine of the soul"; cf. Epictetus, Discourses, 2, 2 1 , I S; 22. Chrysippus wrote a Therapeutics of the Passio,,s; cf. S VF, vol. 3, §474. Cf. also the aphorism attributed to Epicurus by Usener (Epicurea, fr. 22 1 = Porphyry Ad Marcel/am, 3 1 , p. 294, 7-8 Nauck):
"Vain is the word of that philosopher which does not heal any suffering of man."
According to H. Chadwick, The Sentences of Sextus, Cambridge 1 959, p. 1 78, n.
336, this sentence is Pythagorean. Cf. Epictetus, Discourses, 3, 23, 30: "The philosopher's school is a clinic."
16 The Epicurean method must be distinguished from that of the Stoics. According to Olympiodorus, CommePltary on tl1e First Aldbiiltles of Plaw, pp. <>, MT; 54, 1 5ff; 1 4S, 1 2ff Wcsterink, the Stoics cure contraries by contraries; the Pyth11gnrc11n11

17 Cf. below. We find the distinction between what depends on us and what does not depend on us in Epictetus, Discourses, I, 1 , 7; I, 4, 27; I, 22, 9; 2, 5, 4; and Epictetus, Manual, ch. 4.
18 Many Stoic treatises entitled On Exercises have been lost; cf. the list of titles in Diogenes Laertius, 7, 1 66-7. A short treatise entitled On Exercise, by Musonius Rufus, has been preserved (pp. 22-7 Hense). After a general introduction concerning the need for exercises in philosophy, Rufus recommends physical exercises: becoming used to foul weather, hunger, and thirst. These exercises benefit the soul, giving it strength and temperance. He then recommends exercises designed particularly for the soul, which, says Rufus, consist in steeping oneself in the demonstrations and principles bearing on the distinction between real and apparent goods and evils. With the help of these exercises, we will get into the habit of not fearing what most people consider as evils: poverty, suffering, and death. One chapter of Epictetus' Disco1mes is dedicated to askesis (3, 1 2, 1-7). Cf. bc:low . The: treatise 011 Exerdse by the PseudoPlutarch, preserved in Arabic (cf. J. Gildmeister and F. Bilcheler, "PseudoPlutarchos Peri askisefis,"
Rheit1isches Museum NF 27 ( 1 872), pp. 520-38), is of no particular interest in this context.

2 1 The word therapeiai can also mean acts of worship, and this meaning would be entirely possible in Philo's mind. Nevertheless, in the present context it seems to me that it designates the therapeutics of the passions. Cf. Philo Judaeus, On 1/1e Special Laws, I, 1 9 1 ; 1 97; 230; 2, 1 7.
