"the mysterious Platonic bridge between the mathematical and the physical" (31).
This bridge between mathematics and physics can be well explained in the thought of Thomas Aquinas. Mathematical objects have a a foundation in extramental reality, but their notions are completed by an act of the mind. Physical objects have an immediate foundation in reality (e.g. 'stone' in this stone), and mathematical objects have a remote foundation in reality (e.g. 'line' in a 'stone' of this stone). Mathematical objects are "mental elaborations remotely based on real quantity but proximately on the mind's constructive activity" (Maurer, 55).

This article describes a most shocking case of insider pharmaceutical lobbying directly resulting in more sales of opioid, which directly result in deaths.
Aristotle introduced akrasia to explain why we make bad decisions in a moment of weakness even though we know better. The point though is not to just stick to commitments (and thereby have enkrateia, self-control), but to be virtuous (arete) and not worry about out-of-control desires in the first place.
Heinrich Himmler, Joseph Goebbels, and Hermann Göring, and the other leaders of the National Socialist party were horribly brutal, but they were not stupid. They were some of the brightest in the most well-educated country in the world. The same goes with French influenced Marxists such as Pol Pot and the Khmer Rouge. Bertrand Russell is right on many points, but he's terribly wrong to think the enemies of civilization are stupid. Read Machiavelli.
