747 – “Vim coeli reserate viri: venit agnita ad usus: Ignotae videas commoda nulla rei.”

“Discover the force of the heavens O Men: Once recognized it can be put to use: No use could be seen in unknown things.”

–Johannes Kepler


634 – “History moves in contradictions. The skeleton of historic existence, the economic structure of society, also develops in contradictions. Forms eternally follow forms. Everything has only a passing being. The dynamic force of life creates the new over and over again — such is the law inherent in reality.”

–Nikolai Bukharin
