If

1 + 1 = ?

is a **problem**

and

“This is a lie.”

is a **paradox**,

a problem often implies

*the method—*

in this case

**addition**

—with which to solve

the problem,

while a paradox

does not.

If you mistake

a paradox

for a problem,

the more time you spend

applying the method

you think

will solve the problem,

the more time

you may spend

staying stuck.
