Hated by the world
The first time people hear the sage's harsh words they dismiss him as a troublemaker. The second time they dismiss him as an antisocial person with "problems". The third time - and by now his truths are beginning to strike home - they call him "mad". The fourth time, and they are calling for his head!
Society does not hate only what the thinker thinks, but that he thinks. They hate his presumption that he might think for himself. And they hate his superiority when he tells them "I am right to think, and you are wrong for refusing to do so." He is the conscience society never had, and is hated as such.
