Kant- the pyschological ideas- page 69-71

In this section Kant is explaining how our mind cognizes things. He says that "pure reason requires us to seek for every predicate of a thing its own subject, and for this subject which is itself necessarily nothing but predicate, its subject, and so on indefinitely (or as far as we can reach). This section made me think a lot. Have you ever thought about something and just wanted to know everything about it? What is stopping us? The fact that what we see and perceive is basically everything that we know about a subject. For us to learn more we have to go out of our way and learn it. How come our mind just can't let us know that the sky is blue for a certain reason? This section started bringing way out there ideas to my brain but that is why i decided to blog about it. Another thing I was thinking about while reading was haven't you ever wished you can experience everything. Or like hear everything that has ever been said. There is so much out there that we much go seek and unless we do it we would never learn.
