Psychology is explainable by biology: My brain gives me my mind. My biology gives me the neural pathways and endocrine systems that regulate my thinking and my moods.

Biology is explainable by chemistry: My metabolism, with its complex chemical reactions and pathways, energises me and keeps me alive.

Chemistry is explainable by physics: The physics of the atom determines the properties of the elements and their chemical combinations.

Physics is explainable by mathematics: From the cosmologists speculating on the birth of the Universe, to the nuclear scientists chasing elementary particles, mathematics is the language of physics.

Mathematics is dependent upon philosophy: May I assume that there is a difference between one and zero? Can a number system be entirely self-contained and independent of other systems?

Philosophy is dependent upon psychology: My way of perceiving the Universe and the questions I ask about it are dependent upon my personality.
