Argument in informal logic
Argument is an informal calculus, relating an effort to be performed or sum to be spent,
to possible future gain, either economic or moral.
In informal logic, an argument is a connexion between
a) an individual action
b) through which a generally accepted good is obtained.

 
Ex :
a) You should marry Jane (individual action, individual decision)
b) because she has the same temper as you. (generally accepted wisdom that marriage is good in itself, and it is generally accepted that people with the same character get along well).
a) You should not smoke (individual action, individual decision)
b) because smoking is harmful (generally accepted wisdom that health is good).
