John Locke Perception

John Locke was perhaps one of the most influential political philosophers of the modern period. In the Second Treatise of Government, John Locke discusses the move from a state of nature and perfect freedom to a then governed society in which authority is given to a legislative and executive power. His major ideas included liberalism and capitalism, state of nature, state of war and the desire to protect one’s property.

The enlightenment era arose in the modern cultural ideology of the 18th century, as ideas among philosophers had a widespread effect among the society. The age of enlightenment, in western society, projected the rejection of traditional Christianity, western philosophy, intellectual advances, scientific, and cultural life, government legitimacy and authority. Upon the enlightenment period multiple philosophers emerged, the individuals arose to leading figures using reason to understand all aspects of human life. The motivations for the enlightenment came primarily from the Englishmen, John Locke. John Locke was a philosophical influence in both political theory and theoretical philosophy, which was embraced among the era of 1789-1914 and

Berkeley's attempt to popularize his pro-mind conception of the external world, Three Dialogues between Hylas and Philonous, serves to undermine Locke's distinctions between primary and secondary qualities of the external world. In his publication, Berkeley uses dialogue between Hylas and Philnous, which consists of a series of arguments, to determine the most sound theory. Ground rules of the debate consists of: whoever of the two's position avoids skepticism about knowledge of physical objects wins and that if one position can be shown to entail that we cannot know anything about physical objects, consequently that position should be dismissed as absurd (Kelly, 2013). Throughout the arguments, Berkeley weakens Locke's theory of Limited Representationalism by counteracting Locke's with the possibility that instead of “matter” that comprises physical objects in the external world, these objects are simply ideas. Drawing back on Berkeley's catchy motto, “to be is to be perceived”, he proposes three arguments that support his idealist view that the motto encapsulates. The three pieces of support also importantly shed skepticism upon Lockes primary and secondary distinctions involving “matter”. The three statements of support include: The argument that physical

John Locke's theory of knowledge stated that all knowledge is derived from the senses, that are converted into impressions, that are then made into ideas, either simple or complex. Simple ideas are ones that involve only one sense, whereas complex ideas consist of multiple simple ideas being combined to create a vivid one. Ideas have two qualities, primary qualities, and secondary qualities. Primary qualities are things that are perceived the same for everyone, and secondary qualities are the individual perceptions of

Locke’s view one must make an inference to substance; it is not a part of sense-experience. And, he thinks it is a justified inference. General idea of substance is an unknown something that supports accidents. Particular substance is nothing but several combinations

John Locke thought that the ideas or perceptions which we have of objects in the world partially represent the objects as they are in themselves, and so whether they are being perceived. This view of Locke’s is called representative realism. The term realism refers to the view that objects are real or exist apart from perception. And representative means that some of our perceptions accurately represent an object as the thing which it is in itself apart from perception. Locke thought that only some of our ideas or perceptions are accurate representations of the object itself, and that

Locke also believes that people have innate ideas through experiences. He has three explanations for this idea. Firstly, if we had innate ideas, we would know that we have them, which means that if you have ideas they are conscience and everything you think, you think you think. Secondly, if there were innate truths of reason we would all agree on them. Lastly, our memory cannot recall these innate ideas.

Primary qualities, however, are objective and include aspects such as an object’s height and weight (Paquette 212). Through this, Locke claimed that the existence of objects can be made certain due to the primary qualities it possesses (Paquette 212). Similar to Descartes, Locke believed in a sense of existence. However, in his view, the facts from the primary qualities proved the object exists because the object exists within itself (Paquette 212).

Like Descartes, Locke also believed in an external world. As an empiricist, Locke relied heavily on the senses to provide true knowledge (Moore 2002). He shared Aristotle’s belief that the mind is a blank slate, also known as tabula rasa, at birth (Paquette 211). Our sense experiences thereafter provide us with knowledge to fill in those slates (Paquette 211). In Locke’s “Representative Theory of Perception,” also known as Epistemological Dualism, he stated that material objects exist and are separate entities from human beings (Paquette 227). However, he also believed that objects exist in the mind as psychological entities (Paquette 227). Locke concluded that people can taste, smell, touch, and see the external world which, in turn, becomes impressions in our minds (Paquette 227). Descartes and Locke are thus seen to be similar in the sense that they both believed in an external world.

Locke feels that we do not have any innate ideas.  Then the question arises of

John Locke starts off his treatise with the thesis that ideas spring from two fountainheads--sensation and reflection. The former, man acquires from external sensible objects that affect man's five senses--those same senses endowed upon all men by the Creator. Material things outside man's being are the objects of sensation. Through experiencing sensation, man's thinking process gives rise to ideas thereby gaining for the thinking being a certain amount of

Locke discards the suggestion of innate ideas. Locke believes that if we always had innate ideas, it would be impossible for us not to perceive or be aware of them. He believes that if there were innate ideas then they would be universal ideas present

Conversely, Locke felt that individuals gained knowledge through real world experiences. He believed in two kinds of complex ideas: ideas of substances and ideas of modes. In The

All ideas we experience derive from sensations and perception. Sensation obviously uses the bodily senses to receive ideas, whereas reflection uses the body’s own procedures to receive ideas like thinking, believing and doubting. [4] Both of these processes are passive. The corpuscular hypothesis, which Locke expanded on from Boyle’s original thoughts, seems to suggest that everything in existence are colourless, tasteless, soundless and odourless corpuscles of matter. By looking at the bits of matter and their motions, it is possible for us to explain the sensations we gain from primary and secondary

John Locke (1632-1704) was the first of the classical British empiricists. (Empiricists believed that all knowledge derives from experience. These philosophers were hostile to rationalistic metaphysics, particularly to its unbridled use of speculation, its grandiose claims, and its epistemology grounded in innate ideas) If Locke could account of all human knowledge without making reference to innate ideas, then his theory would be simpler, hence better, than that of Descartes. He wrote, “Let us then suppose the mind to be, as we say, white paper, void of all characters, without any ideas: How comes it to be furnished? To his I answer, in one word, from EXPERIENCE.” (Donald Palmer, p.165)
