Single Idea 3937
[filed under theme 12. Knowledge Sources / B. Perception / 2. Qualities in Perception / e. Primary/secondary critique
]
Full Idea
By 'solidity' either you do not mean any sensible quality, and so it is beside our enquiry; or if you do, it must be hardness or resistance, which are plainly relative to our senses.
Gist of Idea
'Solidity' is either not a sensible quality at all, or it is clearly relative to our senses
Source

A Reaction
Berkeley fails to recognise that a quality can have primary and secondary aspects (hot/high temperature). He is right that primary qualities are not directly perceived. They are judgements.
