Book III: On Grief of Mind explained
Cicero argues that the mind's disorders are more dangerous and numerous than the body's, yet less attended to.
What happens
Cicero argues that the mind's disorders are more dangerous and numerous than the body's, yet less attended to. He traces how natural virtue is corrupted from birth by bad habits, false opinions, and societal pressures, and asserts that philosophy can cure grief by showing it is based on opinion, not nature. He advocates premeditation on future evils to lessen their impact, contrasting this with Epicurus's view that such forethought only adds unnecessary misery.

Key passages
“The seeds of virtues are natural to our constitutions, and, were they suffered to come to maturity, would naturally conduct us to a happy life; but now, as soon as we are born and received into the world, we are instantly familiarized with all kinds of depravity and perversity of opinions, so that we may be said almost to suck in error with our nurse’s milk.”
We are born with the potential for virtue, but from infancy we are corrupted by false beliefs and bad habits, as if we absorb error with our mother's milk.
Cicero emphasizes how early societal conditioning distorts our natural inclination toward virtue.
“I knew that my son was mortal.”
I was always aware that my son could die.
Anaxagoras's response to his son's death, illustrating the Stoic ideal of premeditation to lessen grief.
“Wherefore ev’ry man, When his affairs go on most swimmingly, E’en then it most behoves to arm himself Against the coming storm: loss, danger, exile, Returning ever, let him look to meet; His son in fault, wife dead, or daughter sick; All common accidents, and may have happen’d That nothing shall seem new or strange.”
In times of prosperity, a person should prepare for misfortune—loss, exile, family troubles—so that nothing catches them by surprise.
Cicero quotes Terence to advocate for constant mental preparation against life's inevitable hardships.
