Lock’s theory on the primary and secondary qualities are both properties of matter, it is a conceptual distinction in epistemology which means it concerns the nature’s physical reality. For example the five main properties for the primary quality is solidity, motion, extension, number and figure they do not rely on subjective judgments, the issue of accuracy applies to primary quality as well. Secondary quality’s is based four properties; color, smell, taste and sound these quality’s effect people every day lock’s theory is that knowledge that comes from secondary qualities does not provide facts about certain things, secondary qualities is subjected. Lock wanted to see how people would experience the world and how it indicates the error and when it does not.
Berkeley thought that Locke’s theory was false he feels that lock’s view on the primary and secondary qualities was incorrect because he assumes that all thoughts involve mental imagination. Berkeley says that objects appear to change shape or size when moved which I do not find correct, he thinks that if all qualities of objects are secondary, then the primary/secondary is a failure.
If a tree falls in the forest, and no one is around to hear it, does the impact of the tree make a sound? If you’re looking at it from Berkeley’s point of view he would say that objects of the sense exist only when they have been perceived on the other hand john lock would say that when the tree falls it causes a vibrations in the air, but he thinks that in the absence of preserve they don’t get transformed into an experiment of sound. If there are no brains or hearing apparatuses around, then there is no sound.
If a tree stands in the forest, and there is no one there to experience the tree, does the tree exist? If so, exactly in what sense does it exist? According to Berkeley’s theory he thinks that if no one is there to hear or see the tree and the forest, they must either have no existence at all, or else subsist
