[To] accept the conclusions of science, it is necessary that science should conclude. And science never does conclude. It is the whole claim and boast of science that she never does conclude. To conclude means to shut up; and the very last thing the man of science is likely to do is to shut up [...] it is the whole point of science never to be in this sense final or irrevocable. Of course, this does not mean that we shall not work more wisely if we work in the light of the suggestions of science, or take note of the general tendencies of science. It only means that people who use these words ten thousand times a year have not taken note of what they are saying [...] If science had concluded, it would mean almost literally that science had shut up shop.
