The Importance Of Innate Ideas In John LockeBy David Locke

Decent Essays

Another problem with Locke’s insistence that innate ideas do not exist, is that necessary truths, that is, contingent propositions (2+2=4), cannot be acquired through experience alone. If necessary truths exist, that would at least infer that innate ideas exist and are merely revealed through experience for necessary truths are a priori, which implies that innate knowledge exists as a disposition. Beyond this, there is the possibility that we can form an idea without a corresponding sensory impression. While not without its flaws, the argument that one can generate an idea without first being exposed to the relevant sensory experience is illustrated in Hume’s ‘missing shade of blue’ example. Locke claims that in order for an idea to be in the mind, we must be conscious of it, which indicates that there is not much leeway allowed for memory, that is, a power of the mind to revive perceptions it once had. The question then, is whether we can know things without being conscious of them. It seems as though it is possible, but it is important to note that regardless if we can or not, what is unconscious must have once been conscious. For this reason, a potential response Locke would give to Hume with reference to the ‘missing shade of blue,’ is that even if one is able to fill it in, they would still be using their senses in some way to access that knowledge and perhaps it would be “knowledge made out of a long train of proofs,” which highlights the mental fatigue factor in play.
With regards to Locke’s theory of knowledge, he holds that knowledge is divided into three types: intuitive knowledge (knowledge the mind can attain without the need for recognizing something else), demonstrative knowledge (a kind of knowledge cannot occur without the help of previous information), and sensation knowledge (knowledge that results from empirical knowledge of the known object). As such, it follows that our knowledge of our own existence is intuitive, our knowledge of God’s existence is demonstrative, and our knowledge of things present to sense is sensitive. Locke believes that intuitive knowledge is ‘real’ knowledge and the most important degree of knowledge wherein there is no need for inference as “the Mind is at no
