The Art of Tetman Callis

“Neither individual nations nor men can thrive when severed from natural intercourse with their kind; whatever the native vigor of constitution, it requires healthful surroundings, and freedom to draw to itself from near and from far all that is conducive to its growth and strength and general welfare. Not only must the internal organism work satisfactorily, the processes of decay and renewal, of movement and circulation, go on easily, but, from sources external to themselves, both mind and body must receive healthful and varied nourishment.” – Captain A. T. Mahan, The Influence of Sea Power Upon History 1660-1783
