The lack of a suitable vocabulary and an adequate frame of reference, and the absence of any strong and sustained desire to invent these necessary instruments of thought here are two sufficient reasons why so many of the almost endless potentialities of the human mind remained for so long unactualized. Another and, on its own level, equally cogent reason is this: much of the world’s most original and fruitful thinking is done by people of poor physique and of a thoroughly unpractical turn of mind. Because this is so, and because the value of pure thought, whether analytical or integral, has everywhere been more or less clearly recognized, provision was and still is made by every civilized society for giving thinkers a measure of protection from the ordinary strains and stresses of social life. The hermitage, the monastery, the college, the academy and the research laboratory; the begging bowl, the endowment, patronage and the grant of taxpayers’ money such are the principal devices that have been used by actives to conserve that rare bird, the religious, philosophical, artistic or scientific contemplative. In many primitive societies conditions are hard and there is no surplus wealth. The born contemplative has to face the struggle for existence and social predominance without protection. The result, in most cases, is that he either dies young or is too desperately busy merely keeping alive to be able to devote his attention to anything else. When this happens the prevailing philosophy will be that of the hardy, extraverted man of action.
