A step a back before a look a back

Say hello to Backward Extrapolation, how "Equational Poetry" ™ met its Companion?

It’s NOT what one feels that’s important, but rather, how one feels it? —

Poetry is a singularity while The POETRIES plurality, so says The "True Life" POET?

"Equational Poetry" ™ Companion Book is "True Life" mathematics. "Equational Poetry" ™ EXTENSION is "HISTORY" in the making.

Poetry came before mathematics but NOT before the POEM, NOR before The POETRIES, but before "First-philosophy" which means WITHIN The POETRIES-PRIOR, but NOT before "HISTORY" in the making.
