After starting to read the Hume articles, I started to disagree with something he said. "All our ideas or more feeble perceptions are copies of our impressions or more lively ones." And the part where he was saying that even though we can think about something (idea) it never compares to the actual feeling or act. At first, I did disagree with this. Not completely, but I do think that our imaginations can make some things pretty real. Anyway, he got me when he said "a blind man can form no notion of colours" etc. and I thought, well that is true. But now, that makes me wonder, don't blind people dream, and if they do wouldn't they be able to see colors? I know that they would not know WHAT the colors are, or be able to identify them, but wouldn't they still get to see them?
