Speed vs Accuracy

Sir Francis Bacon, a strong advocate of the scientific method, said this (paraphrased):

The fastest person on the wrong path gets farther and farther away from where he desires to finish. On the other hand, a plodder on the proper path, ultimately arrives at the truth.

Bacon was emphasizing the importance of thinking before acting.
