If the men of the Middle Ages... lived in filth and discomfort, it was not for any lack of ability to change their mode of life; it was because they chose to live this way, because filth and discomfort fitted in with their principles and prejudices, political, moral, and religious.... It was in the power of medieval... craftsmen to create armchairs and sofas that might have rivaled in comfort those of today
Aldous HuxleyWe are so anxious to achieve some particular end that we never pay attention to the psycho-physical means whereby that end is to be gained. So far as we are concerned, any old means is good enough. But the nature of the universe is such that ends can never justify the means. On the contrary, the means always determine the end.
Aldous Huxley
