Abstract
The most plausible type of panpsychism explains high-level consciousness as a compound of basic conscious properties instantiated by basic bottom-level physical objects. Arguments for panpsychism stand little chance in the absence of an account that makes sense of basic bottom-level experience; and explains how basic bottom-level experiences yield high-level experiences. This paper tackles the first task. It develops a method for investigating basic bottom-level experience: it identifies constraints, motivated by scientific and philosophical considerations, that force a unique account. Then it applies this method, using quarks as stand-ins for basic but conscious physical objects. It concludes that quark-consciousness is maximally simple ; multiple ; and internal
