People often say that humans have always eaten animals, as if this is a justification for continuing the practice. According to this logic, we should not try to prevent people from murdering other people, since this has also been done since the earliest of times.
—Isaac Singer
synecdoche
A figure of speech in which a part is used to designate the whole or the whole is used to designate a part. For example, the phrase "all hands on deck" means "all men on deck," not just their hands. The reverse situation, in which the whole is used for a part, occurs in the sentence "The U.S. beat Russia in the final game," where the U.S. and Russia stand for "the U.S. team" and "the Russian team," respectively.
