Quotation from Science and Hypothesis by Henri Poincare
“Science is built up of facts, as a house is built of stones ; but an accumulation of facts is no more a science than a heap of stones is a house.”
Science and Hypothesis, Part IV, Ch. IX, trans. W. J. Greenstreet

Poincaré explains why the scientist must select and generalize rather than merely collect.
