Eo ipso

Eo ipso means "by (or from) the thing itself" in Latin and is similar to the sense expressed by the English idioms, "by the same token," "of itself" or "on its own account". It is often used in various schools of philosophy to demonstrate the possibility/impossibility of propositions from their nature. For example, "That I am does not eo ipso mean that I think." The term is also used in law, and it is through law that it was brought into English from Latin.
