In an organic unity bodily members play the same part as reasoning beings among separate existences, since both are fitted for one joint operation. This thought will come home to you the more vividly if you say often to yourself: I am a member of the mighty organism which is made up of reasoning beings. If, instead of a member, you say that you are merely a part, you have not as yet attained to a heartfelt love of mankind. As yet you love not well-doing for its own sake alone, and you still perform your bare duty, with no thought that you are your own benefactor by the deed.
