Abstract: Every day we play games of thought, such as prediction, decision, guess and understanding. These games are indispensable in human production and life, as well as the main content of human civilization and culture. For each of these things, the objective world is a part of the subjective world. This philosophical worldview is a fake but more valuable worldview. This paper analyzes the thought games of decision, prediction, desire, guess, understanding, evaluation, art and religion respectively. Many alternative plans made before decision belong to the subjective world, and one of them will become objective reality. This plan belongs to the objective world, so the objective world is a part of the subjective world. A plan is a systematic decision making over a period of time. Laws, institutions, rules, standards, etc., are systematic decisions for a number of years or all time. In the objective world, there is only the present, without the past and the future. In the subjective world, there can be the past, the present and the future at the same time, so the objective world is a part of the subjective world. This paper also analyzes the conditions for the use of Robert's Rules of procedure.
