“The will is the keystone in the arch of human achievement. It is the culmination of our complex mental faculties. It is the power that rules minds, men and nations.”

“There must be some other possibility than death or lifelong penance ... some meeting, some intersection of lines; and some cowardly, hopeful geometer in my brain tells me it is the angle at which two lines prop each other up, the leaning-together from the vertical which produces the false arch.

“The difference between a millstone and a keystone is a gemstone.”

“You are kept apart that you may be separately fleeced of your earnings. You are made to hate each other because upon that hatred is rested the keystone of the arch of financial despotism which enslaves you both. You are deceived and blinded that you may not see how this race antagonism perpetuates a monetary system which beggars both.”

“Let food be thy medicine and medicine be thy food.”
