claimSubjective idealism differs from dual-aspect monism by asserting that the single substance possesses only mental properties throughout, and that physical properties are observer-dependent and not fully real.
claimSubstance dualism, subjective idealism, and emergent panpsychism may have an advantage in accommodating unity arguments against physicalism, provided that the deflationary view of subjects is rejected.
perspectiveSubjective idealism asserts that the physical world does not exist as a fully real entity but is instead an illusion, as the physical world is fundamentally mental.
claimSubjective idealism interprets the argument from physical causal closure not as evidence of physical events having sufficient physical causes, but as evidence of regularities holding between various kinds of perceptions or experiences.
claimSubjective idealism interprets the previous explanatory successes of science as revealing regularities between perceptions of higher-level complex phenomena and perceptions of lower-level mechanisms, rather than revealing that higher-level phenomena are physically constituted.
claimDual-aspect monism argues that it is as parsimonious as physicalism in its response to the argument from mind–brain correlations, similar to the response provided by subjective idealism.
claimPhenomenalism posits that the physical world consists in potentials for conscious perceptions, distinguishing it from subjective idealism, which posits that the physical world consists in the perceptions themselves.
claimSubjective idealism questions the existence of physical reality, specifically regarding the concept of observer-independence.
claimSubjective idealism addresses unity arguments against physicalism by positing subjects as mental substances in addition to experiences or ideas.
claimMonism is the philosophical view that there is only one kind of stuff or substance, and this category includes physicalism, subjective idealism, property dualism, and dual-aspect monism.
claimSubjective idealism defines the physical world as observer-dependent, meaning it is dependent on the consciousness of external observers.
claimThe interpretation of quantum mechanics known as QBism has been interpreted by some, such as Harvey Brown, as suggestive of subjective idealism.
claimSubjective idealism faces the challenge of explaining why regularities between perceptions hold both within and between subjects, as leaving them unexplained implies they are coincidental.
claimSubjective or antirealist idealism posits that the physical world consists only of appearances or perceptions within minds, such as those of humans, complex animals, or intelligent aliens.
claimSubjective idealism posits that only mental properties are fundamental, while physicalism posits that only physical properties are fundamental.
claimPure panpsychism is a form of objective or realist idealism because it posits that the physical world consists of relations between mental relata that share the same structure as described by physics, unlike subjective or antirealist idealism.
perspectiveExplaining the regularities of perceptions in subjective idealism via God is often viewed as a complicated hypothesis that makes the theory less simple than physicalism.
claimDual-aspect monism avoids the problems of subjective idealism by treating the physical world as observer-independent and possessing the structure described by physics, thereby functioning as a form of realism about the physical world.
claimSubjective idealism, a theory associated with George Berkeley, posits that only consciousness is fundamentally real, while the physical world is an illusion.
claimSubjective idealism explains mind-brain correlations by regarding brain states as perceptions of one subject (a person observing someone else's brain) and conscious states as the perceptions or other conscious states of another subject (the person whose brain is being observed).
claimSubjective idealism requires positing correlations between the perceptions of different subjects, unless the theory is combined with solipsism.
referenceIdealism can be categorized into two types: subjective (or antirealist) and objective (or realist), as noted by Chalmers and Seager (2019a).
claimIf QBism is interpreted as subjective idealism, it faces the problem of explaining why experiences are regularly and predictably organized without an underlying quantum reality.
