A description of the property of monotonicity of Boolean functions using propositional calculus is presented, which allows to use #SAT algorithms for computing Dedekind numbers. Using an obvious modification of Davis-Putnam satisfiability algorithm, Dedekind numbers until the seventh have been calculated. Standard arithmetization of propositional logic allows to deduce Kisielewicz's formula in more transparent way.
