A new variational principle and duality for the problem $Lu=\nabla G(u) $ are provided, where $L$ is a positive definite and selfadjoint operator and $\nabla G$ is a continuous gradient mapping such that $G$ satisfies superquadratic growth conditions. The results obtained may be applied to Dirichlet problems for both ordinary and partial differential equations.
