Our civilization has decided, and very justly decided, that determining the guilt or innocence of men is a thing too important to be trusted to trained men. If it wishes for light upon that awful matter, it asks men who know no more law than I know, but who can feel the things that I felt in the jury-box. When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up its specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.
