If we will attentively consider new born children, we shall have little reason to think that they bring many ideas into the world with them and that "by degrees afterward, ideas come into their minds. Locke allowed that some ideas are in the mind from an early age, but argued that such ideas are furnished by the senses starting in the womb: If we have a universal understanding of a concept like sweetness, it is not because this is an innate idea, but because we are all exposed to sweet tastes at an early age. He took the time to argue against a number of propositions that rationalists offer as universally accepted truth, for instance the principle of identitypointing out that at the very least children and idiots are often unaware of these propositions.
Taken together, they comprise an extremely long and detailed theory of knowledge starting from the very basics and building up. Book I, "Of Innate Ideas," is an attack on the Cartesian view of knowledge, which holds that human beings are born with certain ideas already in their mind. Once he feels secure that he has sufficiently argued the Cartesian position, Locke begins to construct his own theory of the origins of knowledge.
The short answer is: The long answer is Book II. He argues that everything in our mind is an idea, and that all ideas take one of two routes to arrive in our mind: He also classifies our ideas into two basic types, simple and complex with simple ideas being the building blocks of complex ideasand then further classifies these basic types into more specific subcategories.
The vast majority of this book is spent analyzing the specific subcategories of our ideas. Though Book II is primarily an attempt to account for the origin of all our ideas, it also includes two other very important discussions, only tangentially related to the subject of the origin of ideas.
He attempts to show that there are two very different sorts of relations that can hold between the qualities of the outside world and our ideas about those qualities.
The relation between primary qualities e. In contrast, the relation between secondary qualities e. In chapter XXIII, Locke tries to give an account of substance that allows most of our intuitions without conceding anything objectionable. Ideas, however, are still an important part of the picture.
According to the theory of meaning that Locke presents, words do not refer to things in the external world but to the ideas in our heads. Locke, relying heavily on his theory of ideas, attempts to give an account of how we form general terms from a world of particular objects, which leads him into a lengthy discussion of the ontology of types that is, the question of whether there are any natural kinds out in the world or whether all classifications are purely conventional.
Locke begins with a strict definition of knowledge, one which renders most sciences all but mathematics and morality ineligible. Knowledge, according to Locke, is the perception of strong internal relations that hold among the ideas themselves, without any reference to the external world.
The remainder of the book is spent discussing opinion or belief, which is the best we can hope for from nearly all our intellectual endeavors.
Locke is very careful to refrain from speaking as if opinion is "mere opinion;" he is not a skeptic and does not believe that science is futile. On the contrary, he is very eager to claim in the last chapters of theEssay, that we should be satisfied with this level of certitude and that we should continue collecting scientific data with gusto.
Gaining a better and better opinion of the world is a worthy goal, and one that he shares.
He does ask, however, that we be aware that as good as our opinions become, they are never going to reach the level of knowledge.CONTENTS of the NINE VOLUMES.. VOLUME I. Preface to the Works.

Aug 21, · In his “Essay Concerning Human Understanding,” he advanced a theory of the self as a blank page, with knowledge and identity arising only from accumulated experience. In Book IV of An Essay Concerning Human Understanding (), Locke defined knowledge as “the perception of the connexion of and agreement, or disagreement and repugnancy of any of our ideas.” Knowledge so defined admits of three degrees, according to Locke.
