     if conditioon then consequent

For example the statement "every person has a father", i.e. ∀x.∃y. Person(x) ⇒ hasFather(x, y), becomes

     if X is a person then X has a father

Or "the brother of the father is the uncle", i.e. ∀xyz. hasFather(x,y) ∧ hasBrother(y,z) ⇒ hasUncle(x,z), becomes

     if Y is the father of X and Z the brother of Y then Z is the uncle of X
