Our notion of symmetry is derived form the human face. Hence, we demand symmetry horizontally and in breadth only, not vertically nor in depth.

You see, if the height of the mercury [barometer] column is less on the top of a mountain than at the foot of it (as I have many reasons for believing, although everyone who has so far written about it is of the contrary opinion), it follows that the weight of the air must be the sole cause of the phenomenon, and not that abhorrence of a vacuum, since it is obvious that at the foot of the mountain there is more air to have weight than at the summit, and we cannot possibly say that the air at the foot of the mountain has a greater aversion to empty space than at the top.

We are so presumptuous that we should like to be known all over the world, even by people who will only come when we are no more. Such is our vanity that the good opinion of half a dozen of the people around us gives us pleasure and satisfaction.

Fashion is a tyrant from which nothing frees us. We must suit ourselves to its fantastic tastes. But being compelled to live under its foolish laws, the wise man is never the first to follow, nor the last to keep it.

Curiosity is nothing more than vanity. More often than not we only seek knowledge to show it off.

Nature imitates herself. A grain thrown into good ground brings forth fruit; a principle thrown into a good mind brings forth fruit. Everything is created and conducted by the same Master-the root, the branch, the fruits-the principles, the consequences.
