TUERENTUR: rule, or guard, or care for. Most editors wrongly take
_tuerentur_ to be for _intuerentur_, 'to look upon', and regard it as an
intentional archaism. But cf. Rep. 6, 15 (where no archaism can be
intended): _homines sunt hac lege generati, qui tuerentur illum globum quae
terra vocatur_; also _tuentur_ below in 82. -- CONTEMPLANTES IMITARENTUR:
perhaps more Stoic than Platonic; the Stoics laid great stress on the
ethical value of a contemplation and imitation of the order of the
universe. Cf. N.D. 2, 37 _ipse homo ortus est ad mundum contemplandum et
imitandum_; Sen. Dial. 8, 5, 1 _Natura nos ad utrumque genuit, et
contemplationi rerum et actioni_. -- MODO: here _modus_ seems to be the
Platonic το μετριον, or perhaps a reminiscence of the Aristotelian doctrine
of the mean (n. on 46). Translate 'in moderation and consistency of life';
and cf. Off. 1, 93 _rerum modus_ 'moderation in all things'. For
_constantia_ see n. on 4. -- ITA: cf. n. on 16 _et tamen sic_.

78. PYTHAGORAN: see n. to 23. No ancient philosopher held more firmiy than
Pythagoras to belief in the immortality of the soul; it formed a part of
his doctrine of Metempsychosis. He was also noted for his numerical
speculations in Astronomy and Music. With him is said to have originated
the doctrine of the 'harmony of the spheres'. -- QUI ESSENT: 'inasmuch as
they were'. Cicero often tries to make out a connection between Pythagoras
and the early Romans; cf. Tusc. 4, 2; also Liv. 1, 18. -- EX UNIVERSA
MENTE: the world-soul. Diog. Laert 8 gives as Pythagorean the doctrine
ψυχην ειναι αποσπασμα του αιθερος και αθανατον. Similar doctrines occur in
Plato and the Stoics; cf. Div. 1, 110 _a qua (i.e. a natura deorum) ut
doctissimis sapientissimisque placuit, haustos animos et libatos habemus_;
Tusc. 5, 38 _humanus animus decerptus ex mente divina_; Sen. Dial. 12, 6,
7. -- HABEREMUS: imperfect where the English requires the present. A. 287,
_d_; H. 495, V. -- SOCRATES: in Plato's Phaedo. -- IMMORTALITATE ANIMORUM:
this is commoner than _immortalitas animi_, for 'the immortality of the
