The quality of existing by or from oneself; the property of being self-originated or self-sufficient.
From Latin 'a se' (from oneself) + '-ity' (quality of). Popularized in medieval philosophy to express God's absolute independence and non-contingent existence.
If you think about it, literally everything in your life depends on something else—your lunch depends on farmers, your existence depends on your parents—but philosophers said only God has true aseity!
