_studeat ut ipse aemuletur._ This explanation is approved by Bernouf.
Cortius might have added Cat. 7: _sese_ quisque hostem _ferire
--properabat._ "Student," Cortius interprets by "cupiunt."

[2] To the utmost of their power--_Summa ope_, with their utmost
ability. "A Sallustian mode of expression. Cicero would have said
_summa opera, summo studio, summa contentione._ Ennius has '_Summa
nituntur opum vi_.'" Colerus.

[3] In obscurity--_Silentio._ So as to have nothing said of them,
either during their lives or at their death. So in c. 2: _Eorum ego
vitam mortemque juxta aestumo, quoniam de utraque siletur_. When Ovid
says, _Bene qui latuit, bene vixit,_ and Horace, _Nec vixit male, qui
vivens moriensque fefellit,_ they merely signify that he has some
comfort in life, who, in ignoble obscurity, escapes trouble and
censure. But men thus undistinguished are, in the estimation of
Sallust, little superior to the brute creation. "Optimus quisque,"
says Muretus, quoting Cicero, "honoris et gloriae studio maxime
ducitur;" the ablest men are most actuated by the desire of honor and
glory, and are more solicitous about the character which they will
bear among posterity. With reason, therefore, does Pallas, in the
Odyssey, address the following exhortation to Telemachus:

"Hast thou not heard how young Orestes, fir'd
With great revenge, immortal praise acquir'd?

O greatly bless'd with ev'ry blooming grace,
With equal steps the paths of glory trace!
Join to that royal youth's your rival name,
And shine eternal in the sphere of fame."
