“The four-part cure,” is the Greek philosopher Epicurus’ remedy for leading the happiest possible life.
Don’t fear god,
Don’t worry about death;
What is good is easy to get, and
What is terrible is easy to endure
The “tetrapharmakos” was originally a compound of four drugs (wax, tallow, pitch and resin); the word has been used metaphorically by Epicurus and his disciples to refer to the four remedies for healing the soul.
