- Bridge laws(Philosophy of mind, type-identity theory)
- Strict biconditional laws of the form 'P1 ↔ M1' that correlate physical predicates with mental predicates, forming the basis of type-identity theories of mind.
- Intrinsic phenomenal properties(in philosophy of mind)
- The inner, subjective feel or 'what it's like' quality of an experience—like the redness of seeing red—considered as something independent of what the experience does or causes.
- Mental kinds(in philosophy of mind)
- Categories of mental phenomena, like beliefs, desires, or emotions, treated as natural groupings.
- Mental state types(in philosophy of mind)
- Categories or kinds of thoughts, feelings, or experiences—like 'being angry' or 'seeing red'—rather than individual instances of them.
- Nomologically tractable(in philosophy of science)
- Able to be described and understood using scientific laws (the word 'nomological' comes from the Greek word for law).
- Physical kinds(in philosophy of mind and science)
- Categories of physical things or processes, like atoms, neurons, or chemical reactions, treated as natural groupings.
- functional roles(as used in philosophy of mind)
- The jobs or purposes something is designed to do, like how a calculator's functional role is to perform math—in this context, the information-processing tasks the brain performs.
