Leibniz

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

“「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.」”

“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。”
