John Locke's Essay Concerning Human Understanding

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.

Furthermore, Locke’s profound analysis on sources of knowledge contributed to today’s psychological analysis of the unsolved dilemma of nature versus nurture while significantly shaping the foundation of modern psychology. As Locke introduced empiricism in An Essay Concerning Human Understanding, he was an important figure of Enlightenment to foster and alternate the schools of thinking in many spheres including here philosophy and psychology among many others.

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).

These two properties are called primary qualities and secondary qualities. John Locke's tries to explain the difference between primary and secondary qualities in a way that may be confusing for some people. He is generally careful in explaining the differences between the ideas in the mind from what caused these ideas.

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

     Locke instead is an empiricist, and therefore he directly critiques Descartes epistemic system and tries to establish his own foundation of knowledge. Locke believes that our knowledge of the world comes from what our senses tell us. Locke’s theory state that we are all born with a blank slate, tabula rasa, before we

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)

As sensuous properties, says Fichte, are not inherent to the object, but only to the subject, he merely perceives generic, irreducible differences which he is able to catalogue and arbitrarily label with names: red, smooth, tonal. These distinctions make consciousness possible in that without difference sensations, as well as, the distinction between subject and object, consciousness would be an incomprehensible singularity from which nothing could be ascertained. Fichte arrives at the idea of external objects via the Principle of Sufficient Reason, reasoning then that the principle is inherent and necessary for his consciousness; by demanding a cause for his various sensations, the principle seems immediate and inherent because it is at the root of sensation and external object and cannot, therefore, be instantiated by them without circularity. Now, if the principle is a category of Fichte's consciousness and enables him to sense external objects, he feels obligated to concede that "consciousness of the object is only a consciousness of my production of a presentation of the object, which is not recognized as such."
