1217: Thomas Aquinas justification of interest...

 The economic landscape of the High Middle Ages, c. 1000-1300, was one of dramatic transformation. 

  

The stagnation of the early medieval period gave way to a "commercial revolution" characterised by population growth, urbanisation, the rise of international trade fairs, and the increasing use of money. 

  

This burgeoning commercial activity created a tension with the entrenched feudal, agrarian social order and, more importantly, with the dominant worldview of the Catholic Church. 

  

The Church’s teachings, heavily influenced by the Church Fathers like St. Augustine (354 - 430 AD), were deeply ambivalent towards worldly wealth and economic endeavour. 

 

The Bible, 1 Timothy 6:10 states, "For the love of money is a root of all kinds of evil," and is often misinterpreted as saying "money is the root of all evil". 

  

The verse warns that the desire for wealth can lead people to stray from their faith, fall into temptation, and cause themselves "many sorrows". 

  

The verse's main point is about the destructive power of greed, not about money itself. 
  
The scriptural injunctions against the love of money and the ideal of apostolic poverty created a cultural milieu

   

that was inherently suspicious of profit-seeking and commerce, often associating it with avarice, one of the seven deadly sins.

    

Yet Thomas Aquinas had to find a way to justify that some charged a price for lending money. They demanded interest, which constitutes a violation of commutative justice because it creates inequality.

  

However, Aquinas had an ingenious explanation of demanding interest. He introduced the concepts  "lucrum cessans" (ceasing gain) and "damnum emergens" (emerging loss). 

  

If a lender could demonstrate that by lending his money, he incurred a verifiable loss ("damnum emergens"), 

  

such as a missed business opportunity, or if he forfeited a profit he would otherwise have made ("lucrum cessans"), he could licitly charge compensation. 

    

This was not payment for the use of the money *per se*, but restitution for a loss incurred. A borrower could say:

  

Ok, I'll lend you the money, but unfortunately, it means that I can not open my second store now, so I ask you to pay interest for this inconvenience.


This distinction, while intended to uphold the usury prohibition, in practice provided a significant loophole that allowed credit to flow in an expanding economy.

    

It shifted the focus from the inherent nature of money to the concrete circumstances of the lender and the economic consequences of the loan, paving the way for later justifications of interest.

   

Another step in the direction of capitalism and big banking.
