My boss was honest with me today

He pulled up to work with his sweet new car this morning and I complimented him on it.

He replied, "Well, if you work hard, set goals, stay determined and put in long hours, I can get an even better one next year."

Paul Bernays

Died 18 Sep 1977 at age 88 (born 17 Oct 1888).Paul Isaak Bernays was a Swiss mathematician and logician who is known for his attempts to develop a unified theory of mathematics. Bernays, influenced by Hilbert's thinking, believed that the whole structure of mathematics could be unified as a single coherent entity. In order to start this process it was necessary to devise a set of axioms on which such a complete theory could be based. He therefore attempted to put set theory on an axiomatic basis to avoid the paradoxes. Between 1937 and 1954 Bernays wrote a whole series of articles in the Journal of Symbolic Logic which attempted to achieve this goal. In 1958 Bernays published Axiomatic Set Theory in which he combined together his work on the axiomatisation of set theory.
