Experience does not err. Only your judgments err by expecting from her what is not in her power.

Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments.

Blinding ignorance does mislead us. O! Wretched mortals, open your eyes!

To such an extent does nature delight and abound in variety that among her trees there is not one plant to be found which is exactly like another; and not only among the plants, but among the boughs, the leaves and the fruits, you will not find one which is exactly similar to another.

And wisdom be the daughter of experience.

Wisdom is the daughter of experience.
