- Aristotelian categories(in Aristotle's metaphysics)
- Aristotle's system for sorting all the different ways things can exist or be described—like substance, quantity, quality, relation, and others.
- Aristotle
- Aristotle was an ancient Greek philosopher who lived over 2,000 years ago and is one of the most influential thinkers in Western history. He studied nearly every subject—from animals and plants to politics and ethics—and developed practical ways of thinking that shaped how people understand the world. His ideas on logic, nature, and how to live a good life are still taught and debated today because he focused on observing the real world rather than just abstract theories.
- Exhaustive(describing the relationship between X1, X2, and X3)
- A set of options that covers all possibilities with no gaps—like saying a coin must be either heads or tails, with no other outcomes possible.
- Ontological
- "Ontological" refers to questions about what actually exists or is real. It's concerned with the fundamental nature of being—asking "What kinds of things are there?" rather than "How do we know about them?" For example, an ontological question might be whether numbers, ideas, or God actually exist as real things, or if they're just human inventions.
- Ontological grid(how Aristotle's categories function in this argument)
- A complete framework or map that supposedly accounts for and organizes everything that exists.
- principle of non-contradiction(Aristotle's Metaphysics IV 6 1011b13–20)
- The principle that any two contradictory propositions cannot both be true simultaneously.
- species(Bacon's multiplicatio specierum theory adapted to epistemology by Crathorn)
- A representative likeness of an external thing, transmitted causally through a medium; in Crathorn's usage, a material mental quality in the mind that has the same nature as the external thing it represents.
