I am satisfied with the mystery of life's eternity and with a knowledge, a sense, of the marvelous structure of existence - as well as the humble attempt to understand even a tiny portion of the Reason that manifests itself in nature.

This subject brings me to that vilest offspring of the herd mind -- the odious militia. The man who enjoys marching in line and file to the strains of music falls below my contempt; he received his great brain by mistake -- the spinal cord would have been amply sufficient. This heroism at command, this senseless violence, this accursed bombast of patriotism -- how intensely I despise them! War is low and despicable, and I had rather be smitten to shreds than participate in such doings.

To take those fools in clerical garb seriously is to show them too much honor.

Problems cannot be solved by thinking within the framework in which the problems were created.
