Many of the philosophers of the so-called rationalistic school followed Plato in this respect. Besides perception and retention, there are other simple ideas that are derived from the activities of the mind.
Ideas of Substances Summary In asking where we get our idea of substances, Locke finds himself in one of the stickier sections of the Essay. That something, he argues, corresponds to our idea of substance in general or substratum.
Ideas, however, are still an important part of the picture. They include solidity, extension, figure, number, and mobility. Complex ideas are made up of simple ones that must be viewed or taken together. Finally, Locke tries to account for false and fantastical ideas.
By sensation people acquire knowledge of external objects; by reflection people acquire knowledge of their own minds. Obviously, another type of explanation must be found for them.
Self depends on consciousness, not on substance. He had argued that this distinction was necessary because the so-called primary qualities do not change but remain constant regardless of whether they are being perceived by any minds.
Beginning with an account of simple ideas which are derived from the senses, he proceeds to an explanation of the ideas of reflection, perception, space, time, substance, power, and others that are related to these.
He tells us that simple ideas derived from either sensation or reflection are the units out of which human knowledge is composed. Thus, the drunkard knows that away from the greater good when he starts to drink, but is driven by the concern of running out of what he wants most: Thinking takes place only when one is awake.
Any attempt to further the cause of human knowledge must begin by showing the falsity of this position. Obviously, another type of explanation must be found for them.
Thus it is always as to our present sensations and perceptions: This also shows wherein the identity of the same man consists; viz. The very idea of a quality involves dependence, being a quality of something.
Nevertheless, in our minds each of these qualities is separate and distinct. A relation we have in an author of great note, is sufficient to countenance the supposition of a rational parrot.
Beyond that, we have no hint and no hope of getting a hint. Simple ideas include not only the ones that are derived from the senses but also the ones that are derived from the activities of the mind itself.
So what are qualities dependant on, what do they exist in? Neither can we say that it is derived from reflection on the sensations that have occurred, for while these sensations appear in a certain order, there is nothing to indicate that they had to occur in that order.
They may occur in the so-called lower animals. It is in this way that we derive our notions of color, heat, cold, softness, hardness, bitter, sweet, and all the sensible qualities of which one ever becomes aware.
Thus, the limbs of his body are to every one a part of Himself; he sympathizes and is concerned for them. First, he felt that the idea was needed in order to make sense of our language.
Other difficulties arise in connection with this problem, and these will become even more apparent in the light of what he has to say about complex ideas.
Perceptions are present in various degrees, and to some extent they may occur in children even before they are born. Having accepted the empirical method as the only reliable one for an adequate understanding of the phenomenon of human knowledge, Locke was led by the logic of his position into a kind of subjectivism.
This view is called the "bundle theory" of substances, because it regards substances as mere collections of observable properties. Primary qualities are those that matter has constantly, whatever its state.
The degree of perception that is experienced by normal human beings is one of the characteristics that distinguish the human mind from that of the lower animals. He had insisted that such items as size, weight, shape, motion, and number were present in the external objects, whereas color, sound, taste, odor, and feeling exist only in the minds which perceive the objects.This detailed literature summary also contains Topics for Discussion and a Free Quiz on An Essay Concerning Human Understanding by John Locke.
