Coolidge explained Garman's ethics forty years later:

[T]here is a standard of righteousness that might does not make right, that the end does not justify the means, and that expediency as a working principle is bound to fail. The only hope of perfecting human relationships is in accordance with the law of service under which men are not so solicitous about what they shall get as they are about what they shall give. Yet people are entitled to the rewards of their industry. What they earn is theirs, no matter how small or how great. But the possession of property carries the obligation to use it in a larger service...[16]
At his father's urging after graduation, Coolidge moved to Northampton, Massachusetts, to become a lawyer. Coolidge followed the common practice of apprenticing with a local law firm, Hammond & Field, and reading law with them. John C. Hammond and Henry P. Field, both Amherst graduates, introduced Coolidge to law practice in the county seat of Hampshire County, Massachusetts. In 1897, Coolidge was admitted to the Massachusetts bar, becoming a country lawyer.
