Like the watermen who advance forward while they look backward.

I do not correct my first imaginings by my second--well, yes, perhaps a word or so, but only to vary, not to delete. I want to represent the course of my humors and I want people to see each part at its birth.

Courtesy is a science of the highest importance. It is...opening a door that we may derive instruction from the example of others, and at the same time enabling us to benefit them by our example, if there be anything in our character worthy of imitation.

Now, since our condition accommodates things to itself, and transforms them according to itself, we no longer know things in their reality; for nothing comes to us that is not altered and falsified by our Senses. When the compass, the square, and the rule are untrue, all the calculations drawn from them, all the buildings erected by their measure, are of necessity also defective and out of plumb. The uncertainty of our senses renders uncertain everything that they produce.

Almost all the opinions we have are taken on authority and on credit.

Reason has so many forms that we do not know which to choose-Experiment has no fewer.

No wind favors he who has no destined port.
