Ipso facto
Ipso facto is a Latin phrase, directly translated as "by the fact itself", which means that a specific phenomenon is a direct consequence, a resultant effect, of the action in question, instead of being brought about by a previous action. It is a term of art used in philosophy, law, and science.
Aside from its technical uses, it occurs frequently in literature, particularly in scholarly addenda: e.g., "Faustus had signed his life away, and was, ipso facto, incapable of repentance" or "These prejudices are rooted in the idea that every tramp ipso facto is a blackguard".
