A tragic poet will never think of grouping around the chief character in his play secondary characters to serve as simplified copies, so to speak, of the former. The hero of a tragedy represents an individuality unique of its kind. It may be possible to imitate him, but then we shall be passing, whether consciously or not, from the tragic to the comic. No one is like him, because he is like no one. But a remarkable instinct, on the contrary, impels the comic poet, once he has elaborated his central character, to cause other characters, displaying the same general traits, to revolve as satellites round him.
