How would you symbolize the statement "I will love you unless you kiss me"?

Question

logic

Answer 1

I would use the symbol of a jackass.

Answer 2

Some logic books translate 'unless' as a disjunction, while other logic books translate 'unless' as a conditional. The two forms of translation are logically equivalent.

For the English form ‘P unless Q’,  the translations;

P v Q

~Q -> P

are “tied” with respect to truth conditions.  The first translation, P v Q, is easier to apply mechanically once this pattern has been simply memorized.  But the second, ~Q -> P, better reflects human cognition in understanding the English ‘unless’.  For in understanding the English form ‘P unless Q’, ~Q is taken to be an explanatory precondition for P.  An explanatory precondition is more easily processed as the antecedent of a conditional.

Symbolization key:

L = I will love you

K = You kiss me

Disjunction ( v = unless/or):

L v K

Conditional ( -> = if/then):

~K -> L
