These are the two main schools regarding the interpretation of
probability theory.  Crudely speaking, frequentists regard 
probability as the expected frequency with which a given event
would occur in an infinite sequence of trials, while Bayesians
regard it as a measure of ones degree of belief in a proposition.

Naturally both these positions need to be made much more precise
before a sensible discussion can begin regarding their relative
merits.  

The debate between Bayesians and frequentists is relevant to the
debate concerning interpretations of quantum mechanics.  For more
