内容摘要：
Three revolutions are taking place in logical theory and in the foundations of mathematics. First, it is being realized that mathematicians were using before Frege a logic richer than the one which Frege formalized and which has been used as our basic first-order logic ever since. The stronger logic turns out to be the so-called IF logic of Hintikka and Sandu.

Second, set theory cannot be formulated as a first-order axiomatic theory, as most set theorists have done for almost 100 years.

Third, our basic first-order logic should be formulated as a logic of functions and equations, as a kind of universal algebra, and not in terms of predicates and quantifiers.

These developments are not only corrections to earlier mistakes. They open tremendous opportunities for future research including solutions to the main open problems in the relevant fields.
