Meditation 7.13

13. Reasonable beings, constituted for one fellowship of co-operation, are in their separated bodies analogous to the several members of the body in individual organisms. The idea of this will come home to you more if you say to yourself: 'I am a member of the system made up of reasonable beings.' If, however, by the change of one letter, you call yourself a part, you do not yet love men from your heart; well-doing is not yet a joy to you for its own sake; you are still doing it as a bare duty, not yet as though doing good to yourself.
