Berkeley provides (at least) two objections to Lockes - Essay Example In his second Principle, Berkeley claims that objects must be perceived in order to exist, â€Å"for the existence of an idea consists in being perceived† (Berkeley 461). He bases this premise on the evidence that thoughts, passions and imaginative ideas cannot exist without a mind capable of perceiving them. â€Å"And (to me) it seems no less evident that the various sensations or ideas imprinted on the sense, however blended or combined together (that is, whatever objects they compose), cannot exist otherwise than in a mind perceiving them† (471). This goes directly against Locke’s concept of primary properties which are described as properties of an object that are true regardless of who perceives them or even whether they are perceived. Examples of primary properties include the object’s solidity, its figure, its relative motion to its surroundings and its quantity. In the example of a table, primary properties might include its hard surface and open a rea between the legs, its flat surface and height from the ground, its motionless status within the room and its singular status as an object. While Locke says that these things exist whether or not anyone perceives them, Berkeley suggests that none of these elements of the object can be true without someone first perceiving that they’re true. In this, he essentially applies Locke’s concepts of secondary properties to the entire object, eliminating primary properties. â€Å"In truth, the object and the sensation are the same thing and cannot therefore be abstracted from each other† (471). Another area in which Berkeley disagrees with Locke is in the characterization of our understanding. Locke indicates that our perceptions and experiences of the world are learned and shaped by our experiences of innate things that exist in the material world independently of perception while Berkeley
