John Strutt, 3rd Baron Rayleigh Quote

Science is nothing without generalisations... The suggestion of a new idea, or the detection of a law, supersedes much that had previously been a burden upon the memory, and by introducing order and coherence facilitates the retention of the remainder in an available form.

In: William C. McC. Lewis, A System of Physical Chemistry (Volume 1) (p. iv), Longmans, Green and Company. 1918
