Substance

In philosophy, substance means, approximately, that element of an object without which it would not exist. In the millennia-old Aristotelian tradition, as well as early modern traditions that follow it, substances are treated as having attributes and modes. For in-depth articles on the topic, see objecthood and substance theory. For Baruch Spinoza, substance meant also the inner essence or what "stands under" (from the Latin root).

For the chemical concept, see chemical substance.
