"Usury"

Just reading about medieval finance - "due to the prohibition on usury imposed by the Roman Catholic Church".
Hm, forgot about that bit, I typically find it to be difficult for me to even try to force my mind to be pro-catholicism these days... and yet, I guess that was a nice thing then (except if an attempt towards monopoly - remember the alleged very successful banking activities of the templars - up till and I guess possibly ending around Montsegur "lol")?

Not necessarily, idelogoism and wise thinking ... eh, not necessarily the same:
"The first of the scholastic Christian theologians, Saint Anselm of Canterbury, led the shift in thought that labeled charging interest the same as theft. Previously usury had been seen as a lack of charity." (Wikipedia)

And then the end:

"The Roman Catholic Church has always condemned usury, but in modern times, with the rise of capitalism and the disestablishment of the Catholic Church in majority Catholic countries, this prohibition on usury has not been enforced." (Wikipedia)

Okay then ... kind of the "I was wrong in saying 0 but I'd rather be silent and unenforcing than to admit it" is also a practice that I'm not the only one to apply... and maybe not so wrong, given people are mostly like gas, and will try to fill and expand any limits, as well as bend any sort of rules given enough time. So even an enforced zero isn't zero in practice.

Note that in case of a strengthening currency, no interest is profit too :) So typocal.
