“The only thing that has kept the race of men from the mad extremes of the convent and the pirate-galley, the night-club and the lethal chamber, has been mysticism — the belief that logic is misleading, and that things are not what they seem.”

§ I
1910s, At the Feet of the Master (1911)
Context: In all the world there are only two kinds of people — those who know, and those who do not know; and this knowledge is the thing which matters. What religion a man holds, to what race he belongs — these things are not important; the really important thing is this knowledge — the knowledge of God's plan for men. For God has a plan, and that plan is evolution. When once a man has seen that and really knows it, he cannot help working for it and making himself one with it, because it is so glorious, so beautiful. So, because he knows, he is on God's side, standing for good and resisting evil, working for evolution and not for selfishness.
If he is on God's side he is one of us, and it does not matter in the least whether he calls himself a Hindu or a Buddhist, a Christian or a Muhammadan, whether he is an Indian or an Englishman, a Chinaman or a Russian. Those who are on His side know why they are here and what they should do, and they are trying to do it; all the others do not yet know what they should do, and so they often act foolishly, and try to invent ways for themselves which they think will be pleasant for themselves, not understanding that all are one, and that therefore only what the One wills can ever be really pleasant for any one. They are following the unreal instead of the real. Until they learn to distinguish between these two, they have not ranged themselves on God's side, and so this discrimination is the first step.
But even when the choice is made, you must still remember that of the real and the unreal there are many varieties; and discrimination must still be made between the right and the wrong, the important and the unimportant, the useful and the useless, the true and the false, the selfish and the unselfish.

Daedalus or Science and the Future (1923)
Context: Science is as yet in its infancy, and we can foretell little of the future save that the thing that has not been is the thing that shall be; that no beliefs, no values, no institutions are safe. So far from being an isolated phenomenon the late war is only an example of the disruptive result that we may constantly expect from the progress of science. The future will be no primrose path. It will have its own problems. Some will be the secular problems of the past, giant flowers of evil blossoming at last to their own destruction. Others will be wholly new. Whether in the end man will survive his ascensions of power we cannot tell. But the problem is no new one. It is the old paradox of freedom re-enacted with mankind for actor and the earth for stage.
