The statement "Epicurus cautioned his disciples against involvement in politics" is true.
Epicurus, an ancient Greek philosopher, emphasized the importance of pleasure and tranquillity in human life. He argued that politics and public affairs could disrupt tranquillity and prevent true happiness. Epicurus encouraged individuals to cultivate personal relationships, pursue knowledge, and seek pleasure in modest ways. He encouraged creating small, self-sufficient communities called "gardens" to lead a peaceful life free from conflicts and stresses.
