"The new must be seen as urgent and useful. Inapplicable abstractions have no place. We are weary of air castles... Such mastery as, for example, over a piece of ice or over the chemical heat of the sun, must enter the consciousness, as must also mastery of the minutest products of matter. The retardation of spiritual realization is caused by a lack of attention to the manifestations of nature. Losing the power of observation, man loses the ability to synthesize. The abolishment of the use of money will free humanity from the blinders that impair its vision. There are moments of evolution when the walls we erect to contain conventional knowledge become obstacles. The time has come for the emancipation of knowledge, and the assumption of personal responsibility for its use. A free mind has the privilege of searching out new designs based upon unusual combinations. These hitherto undetected threads will lead it to more exalted layers of matter. Beholding play that is timid and limited, the free mind is right to point out new and better combinations. 20."
