The rose we see on the tree, for example, or that we touch with our hand, is that we only have a perception of its smell, its color and its sweetness. Even if we taste it, we will [only] have a perception of its taste. But in none of these cases do we have a sensual perception of the substance where all these phenomena meet. On the contrary, we know this substance only through rational evidence based on primary rational knowledge, as we will point out in future discussions. For this reason, a number of encroachers or experimenters have denied the existence of the material. If he first knows what experience is, then the empirical doctrine, which does not confirm primary knowledge, is falsified; and the presence of necessary human information is confirmed regardless of experience. But if this knowledge needs prior knowledge, it means that we do not know at the outset that experience is a logical criterion whose truth is assured. So how can one demonstrate one`s truth and consider it as a criterion of experience when its truth is not yet certain? The theory of knowledge in dialectical materialism gives first place to the application. It considers that people`s knowledge acquisition is not separate from the application. It also waged a war against all theories it deems false, because it denies the importance of the application or allows the separation of knowledge of the application.38 Locke gives a somewhat unusual name to the knowledge of the outside world. It is often referred to as “sensory knowledge,” but Locke calls this knowledge “sensitive knowledge.” He uses this phrase to mark the different ways in which we become aware of the outside world.
There is something special, according to Locke, how to reach knowledge of the outside world, which distinguishes it from how knowledge of other things, such as mathematical knowledge, is attained. Knowledge of the outside world is known in a “sensitive” way – not “intuitive” or “demonstrative.” Locke cites these three ways of knowing the three degrees of knowledge. Before studying what Locke means when he says that knowledge of the outside world is realized in a sensitive way, it is useful to look at the other ways that Locke thinks we are coming to knowledge – the other “degrees” of knowledge. But the soul can begin to regain its knowledge through the perception of certain ideas and things. This is because all these ideas and things are shadows and reflections of these eternal archetypes and eternal realities in the world in which the soul had lived. When a particular idea is perceived, it immediately moves to the ideal reality it had experienced before being attached to the body. One of the topics that stems from Locke`s anti-sceptic arguments is how Locke describes what it`s like to have knowledge about the outside world, how skeptical concerns are to engage. Individuals may have sensitive knowledge, even if they are not drawn to the lines of the argument itself developed in the essay. In fact, skepticism is neither refuted nor proven false. On the contrary, the skeptic is repelled by arguments that support a likely view that skepticism is false. Locke highlights this point when it comes to his “simultaneous reasons.” These are reasons that are both independent of our sensitive knowledge and unable to prove their skepticism.
