Logical thought is the way to discovering truth. The binary metabolism of digital machinery has made flesh of the old philisophical notions of truth and falsehood. Our minds have always worshipped the idea of truth as the ultimate, supreme God in the pantheon of our superstitions, but now we've been to the moon, are able to store a dictionary on the head of a pin and can converse with people thousands of miles away for the cost of a hotdog and some french fries. Now we believe we have proof that truth is God. Not so, not so.
Truth is just superstition with car keys.
There is no such thing as truth, not the way you think there is. Every proposition you can think of is simultaneously true, and false, and there is no logical contradiction. Clearly, the sky is blue, and at the same time, the sky is most obviously lacking any recognizable shade of blue whatever. You flip the switch and it's the harmony of the light being on with the light simultaneously also being off that keeps the demons of time from pouring through your irises in a tide of certainty. The brute fact of reality's existence presents the mechanical parts of what we are with a puzzle that they simply can't get their hooks and gears around.
