Humean view of the mind and mental activity
Uncle Dave’s meaning
In the questions posed by Uncle Dave, he meant to unravel the way inquiry objects are either matters of fact or mere ideological relations, which is basically the difference between synthetic and analytic propositions. According to him analytical propositions are proved by demonstration, whilst the synthetic propositions are solely manifested via experience (Fieser, p.289). Besides, Uncle Dave hints that matters of fact or substance are totally a creation of experience and dismisses the view that they can be generated via abstract reasoning. According to him, Uncle Dave, every aspect or matter follows its cause, and that they are completely different from one another. In inquiring into how a person can justifiably deem that experience leads to any conclusions concerning the world, he demonstrates how an agreeable argument for the reliability of experience can be emphasized neither on experience nor demonstration.
Hume as well means that it is part of the natural philosophy to explicate the working of sensation. According to him, the most fundamental aspect of sensation is "perceptions", and it is in two forms: ideas and impressions. With impressions, Uncle Dave, seems to suggest that it is more forceful and vivacious when compared to ideas (Turbayne, p.298). Basing on his inquiries, impressions also come in two forms: impressions of reflection and impressions of sensations. Lastly, ideas can, via belief, be made vivacious and forceful enough to be distinguished from impressions; however, Uncle Dave seems to suggest that the basic distinguishing characteristic that demarcates ideas from impressions is that ideas are causally reliant upon the impressions.
The sister he thinks is wrong and what is wrong
Hume's theory is centered on the notions of dispositions and propensities (Yandell, p.77). Therefore, a disposition is a settled the mind state to call up a particular thing when it is displayed with the impressions of a specific character. In other words, the imagination, if subjected frequently to something, develops certain habits (Pylkko%u0308, p.189). It actually comes to anticipate the concurrence of perceptions that past experiences exhibited. Therefore, having worked with the same characters, in previous topics, whereby Melinda had to convince Melissa on rational grounds that souls exist, it goes without saying that Uncle Dave thinks Melissa is wrong, and she is wrong over excessive skepticism or also called the Problem of Induction.
Justifications that one of the sisters is wrong
Uncle Dave will justify his standthat, although the testimony has some force, it is not quite as strong as the straight evidence of the senses. With this said, he will then provide some reasons that attempt to unravel why people may have a foundation for trust in peoples testimonies: First, that because the memory of humans can be relatively tenacious; second that because people are usually inclined to reveal the truth, and very much mortified of telling falsities. In other words, the reasons can only be trusted and relied on to the point that they are derived or conform to experience.
The defense of the sister’s view on rational grounds
The sister may defend her viewbasing on the fact that, in life, there are numerous common beliefs that cannot be explicated as enlivened ideas. In her defense, se would argue that when people form an inference basing on the historical traces evidence, as well as the reason from an existing textual impression to the past subsistence of a historical personage, then, the resultant conviction cannot be accredited to the impressions of the aspects before them.
