The central concept of the system of philosophy developed in this text is that of meaning. This is applied to logic as a theory of meaning, rather than the proof theory of formal logic. Time is assymetric - an arrow. This concept is applied to the laws of nature which have no arrow of time. In the philosophy of mathematics the same emphasis is on meaning using the ideas of Sir William Rowan Hamilton on the ordinal character of numbers, the real numbers, the scalar numbers and the extension to vectors. The problem of God's existence is one of meaning - not proof. This is directly related to the concept of the universe having a beginning or being eternal. The logical universe - the cosmos - is conceived as one reality existing in space and time which is assymetric and corresponds to the real universe.
