At the end, Antony says Brutus was "the noblest Roman of them all" and also commented that "Nature might stand up and say 'This was a man.'"

Philosophically, Antony is commending Brutus for being the one person to follow his own ideals and beliefs..... all of which were based on the good of the Roman people. Brutus' actions were unselfish. He had no ulterior motives, no desire for power or personal gain. He didn't lower himself by using manipulation or deceit. He simply fought for what he believed in.... the Roman Republic. Antony respects him for this.
