Coleridge has a shrewd doubt as to what sort of a character Shakespeare meant his Brutus to be. For, in his thinking aloud just after the breaking of the conspiracy to him, Brutus avowedly grounds his purpose, not on anything Cæsar has done, nor on what he is, but simply on what he may become when crowned. He "knows no personal cause to spurn at him"; nor has he "known when his affections sway'd more than his reason"; but "he would be crown'd: how that might change his nature, there's the question"; and,

Since the quarrel

Will bear no colour for the thing he is,

Fashion it thus; that what he is, augmented,

Would run to these and these extremities;

And therefore think him as a serpent's egg

Which, hatch'd, would, as his kind, grow mischievous,

And kill him in the shell.

[[II, i, 28-34].]

So then Brutus heads a plot to assassinate the man who, besides being clothed with the sanctions of law as the highest representative of the state, has been his personal friend and benefactor; all this, too, not on any ground of fact, but on an assumed probability that the crown will prove a sacrament of evil, and transform him into quite another man. A strange piece of casuistry indeed! but nowise unsuited to the spirit of a man who was to commit the gravest of crimes, purely from a misplaced virtue.
