Calculemus

"The only way to rectify our reasoning is to make it as tangible as that of the mathematicians, so that we can find our errors at a glance, and when there are disputes among persons, we can simply say: calculemus! (let us calculate) without further ado, to see who is right.'"

—Gottfried Wilhelm von Leibniz
