We exist inside a Game of Thinking. We call it the universe, life, reality. But it is the Game of Thinking, a game not played by us, but by thought. Thinking is a fact; everything else is theory. Thought wants us to think. If that was not true, we would be able to stop thinking. But we are not. Thoughts are like zombies. One on one we can deal with them. When they come in bunches, we go under. In order for war to stop, people need to do more than lay down their weapons; they need to lay down their thoughts. Our thinking process runs our lives, yet we do not control it, create it, or guide it. Nor can we switch it off. For it to be real, freedom has to not be a thought. By acquiring more thought, thought acquires you. By acquiring less thought, you acquire you. There is no need to understand black holes or string theory. Those things don't matter, and they may not even exist. There is, likewise, no need to understand ourselves. The benefits of understanding a fool are minimal, and we are all fools. But there is a need to understand understanding itself, which is the Game of Thinking. This book is the first of its kind that questions what is never questioned, namely thinking itself. There are good reasons why it is not questioned, called into doubt, unmasked. One is that it doesn't make sense to do so. Another is that we are trapped. Other reasons we will get to. But we will question thinking, from as many angles as possible. The purpose of this book is to acquire less thought, not more.
