In our reasonings concerning matter of fact， there are all imaginable degrees of assurance， from the highest certainty to the lowest species of moral evidence.
在我们推理关于事实的过程中，有各种可能的确证程度，从最高的确定性到最低级别的道德证据。
生活是一首歌，唱出来吧。
The best way to predict the future is to invent it.
O homem só é verdadeiramente livre quando reconhece a sua dependência dos outros.
