Kita seharusnya memiliki lebih sedikit perselisihan di dunia jika kata-kata diambil apa adanya, tanda-tanda ide kita saja, dan bukan untuk hal-hal itu sendiri. Asli: We should have a great fewer disputes in the world if words were taken for what they are, the signs of our ideas only, and not for things themselves.

— John Locke
