The deadliest enemies of nations are not their foreign foes; they always dwell within their borders. And from these internal enemies civilization is … - William James

Now in all of us, however constituted, but to a degree the greater in proportion as we are intense and sensitive and subject to diversified temptations, and to the greatest possible degree if we are decidedly psychopathic, does the normal evolution of character chiefly consist in the straightening out and unifying of the inner self. The higher and the lower feelings, the useful and the erring impulses, begin by being a comparative chaos within us — they must end by forming a stable system of functions in right subordination. Unhappiness is apt to characterize the period of order-making and struggle.

There are moments of sentimental and mystical experience. . . that carry an enormous sense of inner authority and illumination with them when they come. But they come seldom, and they do not come to everyone; and the rest of life makes either no connection with them, or tends to contradict them more than it confirms them. Some persons follow more the voice of the moment in these cases, some prefer to be guided by the average results. Hence the sad discordancy of so many of the spiritual judgments of human beings; a discordancy which will be brought home to us acutely enough before these lectures end.

Our normal waking consciousness . . . is but one special type of consciousness, whilst all about it, parted from it by the flimsiest of screens, there lie potential forms of consciousness entirely different. We may go through life without suspecting their existence; but apply the requisite stimulus and at a touch they are all there in all their completeness . . . No account of the universe in its totality can be final which leaves these other forms of consciousness quite disregarded.
