This for me is a magical principle more-so than a physically obvious quality of matter.
All materials have “virtues”.
Such as this one resists heat, or that one conducts electricity.
“Virtues” are forms of effective-power.
Now when a man or woman has virtues, they may have fine memory,
or they may be able to run a long distance.
Human virtues have to do with desirable qualities, but what makes
them desirable is nature. Subjects are naturally occuring.
The core of the finest philosophy is relative to virtues.
“Wisdom” is a category of certain types of virtue.
The main step is to learn the difference between vices and virtues.
For example, entropy is part vice and part virtue.
The whole thing is alchemical.
