Caesar was the first to see it.
Cicero would have seen it, but that the idea was so odious to him that he could not acknowledge to himself that it need be so.

His life was one struggle against the coming evil--against the time in which brute force was to be made to dominate intellect and civilization.

His "cedant arma togae" was a scream, an impotent scream, against all that Sulla had done or Caesar was about to do.

The mischief had been effected years before his time, and had gone too far ahead to be arrested even by his tongue.
Only, in considering these things, let us confess that Cicero saw what was good and what was evil, though he was mistaken in believing that the good was still within reach.
Marius in his way was a Caesar--as a soldier, undoubtedly a very efficient Caesar--having that great gift of ruling his own appetites which enables those who possess it to conquer the appetites of others.
It may be doubted whether his quickness in stopping and overcoming the two great hordes from the north, the Teutons and the Cimbrians, was not equal in strategy to anything that Caesar accomplished in Gaul.

It is probable that Caesar learned much of his tactics from studying the man[oe]uvres of Marius.
