This fragmentary essay defends the philosophical life of contemplation against the Stoic emphasis on political engagement. Though surviving only in incomplete form, it makes a compelling case that withdrawal from public life can itself be a form of service — by contributing to wisdom that benefits all of humanity.
The essay explores the tension between duty and reflection, arguing that the philosopher's leisure is not idleness but the highest form of activity.
"This greater commonwealth we are able to serve even in leisure — nay, I am inclined to think, even better in leisure."
