Leibniz

“糾正我們推理的唯一方法是使其像數學家一樣具體，以便我們能夠一目了然地找到錯誤，當人們之間有爭議時，我們可以簡單地說：讓我們計算。”

“「The only way to rectify our reasonings is to make them as tangible as those of the Mathematicians, so that we can find our error at a glance, and when there are disputes among persons, we can simply say: Let us calculate.」”

“「Music is the pleasure the human mind experiences from counting without being aware that it is counting.」”
