I like to spend a good bit of my time thinking about what my concepts of belief, thought, and knowledge are composed of. After a while, I decided that my concept of truth really isn't as significant to me as my concepts of belief, thought, and memory. I came to this conclusion because I am unsure of whether or not I am capable of determining if something that I previously did actually ever happened, but I am capable of believing that it did and am capable of physically retreiving a memory that I associate to a hypothetical event that may or may not have occured. Maybe my memories were rearranged or maybe God placed them there, but I believe that I exist and that I have beliefs, thoughts, and memories. Am I normal for thinking this deeply into beliefs, thoughts, memories, and truth?
