I need to pick out some key concepts from the following passage, and I need a second opinion. What do you think the key concepts are/ summary?
And so he lives on, yielding day by day to the desire at hand. Sometimes he drinks heavily while listening to the flute; at other times, he drinks only water and is on a diet; sometimes he goes in for physical training; at other times, he’s idle and neglects everything; and sometimes he even occupies himself with what he takes to be philosophy. He often engages in politics, leaping up from his seat and saying and doing whatever comes into his mind. If he happens to admire soldiers, he’s carried in that direction, if money-makers, in that one. There’s neither order nor necessity in his life, but he calls it pleasant, free, and blessedly happy, and he follows it for as long as he lives. (Plato, Republic: XIII, 561c-d, p. 286)
