In other words, the person realizes their knowledge and can use that knowledge appropriately. This is someone who is fully utilizing the senses. The first two cases that Aristotle presents are examples of potential scientific knowers due to the fact the first was able to learning from and the second due to having the knowledge of grammar and arithmetic but not using …show more content…
He explains that perception is both external and particular. Aristotle states how the perception of productive things is external or goes through the senses such as what is visible and audible. In contrast, Aristotle states that scientific knowledge holds a universal component and are embedded in the soul. The result is that he claims that it is up to “us” or the individual to understand whenever we wish (potentiality) yet we cannot perceive whenever we desire to due to the fact a perceptible object must be present to
