  The concept of a random Lagrangian is proposed. It is considered as a basis
for a new view of the old problems such as renormalization, nonzero vacuum
energy and the anthropic principle. It gives rise to nontrivial consequences
both in cosmology and in particle physics. It is shown that some of them could
be checked in the nearest future. Scalar-tensor models of gravity are a direct
and necessary consequence of this approach.
