What was Francis Bacon's contribution to the scientific revolution during the 17th century

In 1620, around the time that people first began to look through microscopes, an English politician named Sir Francis Bacon developed a method for philosophers to use in weighing the truthfulness of knowledge. While Bacon agreed with medieval thinkers that humans too often erred in interpreting what their five senses perceived, he also realized that people's sensory experiences provided the best possible means of making sense of the world. Because humans could incorrectly interpret anything they saw, heard, smelled, tasted, or felt, Bacon insisted that they must doubt everything before assuming its truth.
