 Frege took the connection between semantic values and ontological commitments to be a very close one. For on the above analysis,  (24)  supports two kinds of existential generalizations: not just to \(\Exists{x}\mstop\mathbf{M}(x)\) (which is true just in case there exists some object which is mortal) but also to \(\Exists{F}\mstop F(s)\) (which is true just in case there exists some concept under which Socrates falls). According to Frege, this shows that sentences such as  (24)  are ontologically committed not just to an object but also to a concept.
