Math and Logic Puzzles: Redux

[Something_Smart]

Or, if you prefer a different kind of puzzle, have a cryptoquote to solve:

AQUM ITW PMTOJ JN FM AQXMK, TOK ZVYQNWQJG PVWJ FM CMBJ TAQXM. NOM PVWJ OMXMY, UNY ISTJMXMY YMTWNO, JVYO SQW FTZC NO AQUM. —MAMTONY YNNWMXMAJ

Spoiler:

Life was meant to be lived, and curiosity must be kept alive. One must never, for whatever reason, turn his back on life. -Eleanor Roosevelt

I don't know much about cryptogram techniques, but with this one I guessed that "JN FM" was "TO BE", then saw that would make the author's name "E_E..." which immediately broke the whole thing open.
