observation

In short, men will find out that the men of our days were wrong in first multiplying their needs, and then trying, each man of them, to evade all participation in the means and processes whereby those needs are satisfied; that this kind of division of labour is really only a new and wilful form of arrogant and slothful ignorance, far more injurious to the happiness and contentment of life than the ignorance of the processes of Nature, of what we sometimes call science, which men of the earlier days unwittingly lived in. They will discover, or rediscover rather, that the true secret of happiness lies in the taking a genuine interest in all the details of daily life.
