Berkeley's Idealism
Evaluate Berkeley's attack on material substance and his account of a reality composed of minds and ideas.
How to study A-level Philosophy
Learn each position as an argument, connect it to its strongest objection and reply, then decide what conclusion the dialectic supports.
Core concepts
Concept 1
Berkeley argues that sensible objects are collections of ideas and that existence for such objects consists in being perceived.
Exam cue: Distinguish denying matter from denying the ordinary objects of experience.
Concept 2
His likeness principle and attack on the primary-secondary distinction challenge the indirect realist picture of material objects resembling ideas.
Exam cue: Test whether the master argument confuses imagining an object with imagining it unperceived.
Concept 3
The master argument targets the alleged conceivability of an unperceived sensible object, while God explains continued order and existence.
Exam cue: Explain exactly what God's perception is meant to secure.
Targeted study blocks
Specified core
Secure the claim and its place in the debate
Connect Berkeley's critique of material substance to his positive idealism and assess its treatment of illusion, hallucination, continued existence and solipsism.
Philosophical work
Reconstruct, challenge and judge the argument
Separate the attack on indirect realism from the case for idealism, then judge whether idealism solves or merely relocates perceptual problems.
Risk pitfalls and guardrails

Memory anchors

Esse est percipi
For sensible objects, to be is to be perceived.

An idea can resemble only another idea, not a mind-independent material quality.
Master argument
The master argument challenges the conceivability of an unconceived sensible object.
Berkeley's God
God's continuous perception secures the order and continued existence of sensible objects.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
