[filed under theme 14. Science / B. Scientific Theories / 8. Ramsey Sentences ]

The 'quantifier' says whether anything exists for the variable to be

Gist of Idea

Mental terms can be replaced in a sentence by a variable and an existential quantifier

All knowledge needs systematizing, and the axioms would be the laws of nature [Ramsey]
Causal laws result from the simplest axioms of a complete deductive system [Ramsey]
Asking 'If p, will q?' when p is uncertain, then first add p hypothetically to your knowledge [Ramsey]
