This essay is a system of mind based upon Platon, saint Augustine and Kant philosophical systems. Independent criteria are necessary for mind to judge experiment. Criteria are either relative determinations of perceived objects of the experimental world kept in mind by the memory, or absolute concepts such as freedom and truth or space and time. These absolute concepts cannot be copies of objects of the experimental world, because we have no means to perceive them. We can only perceive relative objects because perception is itself a relation. Mind has a direct access to these absolute concepts. This essay is in line with the Hegelian separation between philosophy and theology, i.e. between the transcendental and the theological worlds.
