St Thomas Aquinas apparently enumerated them. I don’t know the chapter/verse. Sorry.
Crucially, St Thomas Aquinas…“connected” the human virtues with the supernatural virtues. (see near the bottom of this post).
The human virtues are those habits or firm dispositions (to do the good) we can develop as humans, without believing in God, being Baptized.
The 4 main ones are: Prudence, Justice, Temperance, Fortitude. The “64” you note are all “derivative” of these main 4 virtues, also called the Cardinal virtues.
Prudence…as the CCC says is the “charioteer” of the other virtues…applying just the right amount of each of the other 3 Cardinal virtues for a given situation.
One example of a “smaller” or child virtue to the cardinal virtue of temperance is: the spirit of poverty (or the virtue known as detachment)…being able to throttle back our inclination to covet things or possess things…created goods, items that whet our appetites or passions.
Another interesting example of one of these lesser/smaller virtues is the virtue of Cheerfulness.
Cheerfulness is actually a sub virtue to the cardinal virtue of JUSTICE. We owe someone our cheerfulness. This might strike someone as wrong headed, but it’s not. In order for someone to live well and more pleasantly they are “owed” our cheerfulness. Providing our cheerfulness helps them pursue the good as it were…so we owe them our cheerfulness.
Some people recently…and they may be right say that in the case of our spouse or children…cheerfulness is a matter of justice…but in the case of others…our cheerfulness is really part of the virtue of Charity.
I love this last example.
Aquinas connected up the human virtues to the supernatural (aka Theological) virtues of Faith, Hope, and Charity.
These virtues are considered “infused” virtues…God infuses in us these virtues…we don’t “generate” our own faith, hope or love.
We get more of these virtues not by practicing them, but by asking God confidently for more of them in prayer.
