The greatness of work is inside man.

The line expresses a central theme of John Paul II’s “theology of work”: work’s true dignity does not lie primarily in what is produced, nor in economic value or social prestige, but in the worker as a person. “Greatness” is located “inside man” because work is a human act—an expression of freedom, responsibility, creativity, and moral growth. Read this way, the quote pushes back against treating labor as merely a commodity or workers as instruments. It also implies that any evaluation of work (including its organization and rewards) should be measured against the good of the person who performs it.
