  We consider one problem that was largely left open by Rudolf Carnap in his
work on inductive logic, the problem of analogical inference. After discussing
some previous attempts to solve this problem, we propose a new solution that is
based on the ideas of Bruno de Finetti on probabilistic symmetries. We explain
how our new inductive logic can be developed within the Carnapian paradigm of
inductive logic-deriving an inductive rule from a set of simple postulates
about the observational process-and discuss some of its properties.
