Immanuel Kant,
Perpetual Peace — SupplementsI. Of the Guarantee of Perpetual Peace…
(1795)
“ Among all the means of power subordinate to the regulation of the State, the power of money is the most reliable, and thus the States find themselves driven to further the noble interest of peace, although not directly from motives of morality. Hence wherever war threatens to break out in the world, the States have an interest to avert it by mediations, just as if they stood in a constant league with each other for this purpose. Thus great combinations with a view to war can but very rarely occur from the very nature of things, and still more rarely can they succeed. ”
