Notable Quotes

Just as deduction should be supplemented by intuition, so the impulse to progressive generalisation must be tempered and balanced by respect and love for colourful detail. The individual problem should not be degraded to the rank of special illustration of lofty general theories. In fact, general theories emerge from consideration of the specific, and they are meaningless if they do not serve to clarify and order the more particularised substance below. The interplay between generality and individuality, deduction and construction, logic and imagination -- this is the profound essence of live mathematics. Any one or another of these aspects of mathematics can be at the centre of a given achievement. In a far-reaching development all of them will be involved. Generally speaking, such a development will start from the "concrete" ground, then discard ballast by abstraction and rise to the lofty layers of thin air where navigation and observation are easy. After this flight comes the critical test of landing and reaching specific goals in the newly surveyed low plains of individual "reality". In brief, the flight into abstract generality must start from and return to the concrete and specific.
-- Epigraph to in 1972: George F. Simmons: Differential Equations
