Which sentence in this excerpt from "Self-Reliance" clearly conveys the spirit of individualism that Ralph Waldo Emerson held?

I read the other day some verses written by an eminent painter which were original and not conventional.

The sentiment they instil is of more value than any thought they may contain.
To believe your own thought, to believe that what is true for you in your private heart is true for all men,--that is genius.
