An idea is always a generalization, and generalization is a property of thinking. To generalize means to think.
Georg Wilhelm Friedrich Hegel (August 27, 1770 November 14, 1831) was a German philosopher born in Stuttgart, Wrttemberg, in present-day southwest Germany. His influence has been widespread on writers of widely varying positions, including both his admirers (F. H. Bradley, Heidegger), and his detractors (Kierkegaard, Marx).
