Simple and modest is the work of philosophy

The George Long translation of 1862:

Simple and modest is the work of philosophy. Draw me not aside to indolence and pride. Marcus Aurelius.  Meditations.  Book 9.

Chrystal's 2017 rendering based on the Foulis translation of 1742:

The work of philosophy is simple and modest. Lead me not astray in pursuit of a vainglorious stateliness. Marcus Aurelius.  Meditations.  Book 9.
