“[T]he general principles which regulate our conduct in business are identical with those which regulate our deliberations, our selections between alternatives, and our decisions, in all other branches of life. And this is why we not only may, but must, take our ordinary experiences as the starting point for approaching economic problems. We must regard industrial and commercial life, not as a separate and detached region of activity, but as an organic part of our whole personal and social life; and we shall find the clue to the conduct of men in their commercial relations, not in the first instance amongst those characteristics wherein our pursuit of industrial objects differs from our pursuit of pleasure or of learning, or our efforts for some political and social ideal, but rather amongst those underlying principles of conduct and selection wherein they all resemble each other; for only so can we find the organic place of industry in our conception of life as a whole.”

—Philip H. Wicksteed, The Commonsense of Political Economy, 1910
