I understand how the material conditional works and it's really nice when using it in propositional logic, but in English I almost lose my mind trying to identify which part of a conditional sentence is necessary or sufficient.
Example:
"Jim can join our club, assuming that he's a good person"
"Parties subject to the aforementioned clause shall pay a fine no greater than $500.00 on the condition that they are over the age of 18"
"Provided that they all pay, the basketball team will be able to compete in the tournament"
Thanks!
