Chatterbox: Down to Earth

Philosophy!

I would consider philosphy to be the single most important invention in human times. Without it, there would be no wheel, no technology, no mathematics, no religion, nothing created by people. Here's my philosophy (don't be offended)

Things only exist as how we can sense them. I sese my calculator to be blue, therefore for all intents and purposes, it is blue. I sense my fingers to be typing, therefore for all intents and purposes, they they are typing. We can't tell what matter 'really is' as we are limited by our senses. There is, in one section, your mind, where, you are trapped, only able to peek through the window of our senses, which may be shaded. Outside is reality, but one cannot know what it actually is, as we cannot observe anything except what our senses tell us. I could be upside down, dancing witha pony, but as I sense I am sitting at my computer, that is only what I can know. In the mind, there are you thoughts and feelings, where you intepret things. You all could sense the world very differently than me, but we'd refer to it the same way, as we'd think we'd be seeing the same thing. Your 'red' could be my 'blue' but we both call it red, so it is red. In fact, I can't know whether you actually exist or not, or if you are just chat-bots programmed to fool me. But, I seriously doubt that, as you all act very human. So, in short, we can only sense the world as we are able to, and we can never know what reality really is.

So, what are you views on the world?
