Summary
This quote suggests that individuals have become so engulfed in their respective professions or occupations that they have blinded themselves to the essence of their own humanity. Rather than maintaining a sense of individuality and autonomy, people conform to the demands and expectations of their work, essentially reducing themselves to mere instruments or tools within the grand machinery of their trade. It highlights the potential loss of identity and personal growth that can occur when one becomes excessively consumed by their vocational pursuits.
