We propose the acceptance of Interactionist Cartesian Dualism and the reality of large, extra spatio-temporal dimensions. After presenting arguments for the plausibility of those ideas, we develop a scenario, along with the necessary mechanisms, which lead to an answer to our thematic question. In short, the answer is that aims and intentions precede mathematics which in turn precedes our Big-Bang-initiated 4D world. Aims and intentions give rise to mathematics, not the other way around. We notice that this proposal suggests new approaches to understanding Cosmogony.
