Charles Ellicott Commentary 1 Corinthians 11:14

"Doth not even nature itself teach you, that, if a man have long hair, it is a dishonor to him?" — 1 Corinthians 11:14 (ASV)

Nature itself.—This may mean either “the native inborn sense of what is seemly” as contrasted with revelation; or it may signify the ordinary and evident arrangement of things in creation. Probably the former is the true meaning of the passage, which refers to the fact that the Gentiles, who had no direct revelation, did (by regarding long hair as a woman’s glory) by nature the things contained in the Law (Romans 11:14).
