Question

In describing Luca Pacioli’s Summa de Arithmetica, Jacob Soll writes “Commerce now had a rhetoric, a mode of argument and proof.” What is he saying with this statement? Did this only apply in the 1400s, or does his statement apply today as well?

Answer 1

This statement will apply today as well because commerce will always have a rhetoric which is a mode of argument and mode of proof.

Commerce is always based upon high degree of negotiation between two parties which are based upon previous informations and related knowledge which are proved in nature and there is always a argument to fix a certain tradable price so that transaction could be executed and hence it will lead to commerce having a rhetoric with proof and mode of argument.

One need to have a high degree of skill in order to derive various kinds of data which are hidden in nature and to be able to generate data will have a high competitive edge in the field of commerce so it will also have a mode of argument based in order to support its theories so, the statement will always hold true.
