Question 18 (1 point) George Berkeley's basic difference with John Locke was the Berkeley's argument that there are only complex ideas. there are no primary qualities. there are only primary qualities. there is a one -to-one correspondence between physical objects and subjective perceptions.

The correct answer is **there are no primary qualities.**<br /><br />John Locke argued that objects have primary qualities (inherent properties like size, shape, and motion) and secondary qualities (qualities perceived by the senses, like color, taste, and smell, which are caused by the primary qualities but don't exist in the object itself). Berkeley disagreed, arguing that *all* qualities are secondary, meaning they exist only in the mind of the perceiver. He believed that "to be is to be perceived." There are no mind-independent qualities.<br />
