He who recognizes this, therefore, feels impelled to look for a way which leads beyond a one-eyed, colour-blind conception of the world. It is the aim of this book to show that such a way exists and how it can be followed. Proof will thereby be given that along this way not only is a true understanding achieved of the forces already known to science (though not really understood by it), but also that other forces, just as active in nature as for example electricity and magnetism, come within reach of scientific observation and understanding. And it will be shown that these other forces are of a kind that requires to be known to-day if we are to restore the lost balance to human civilization.
