Repeat the steps of observation, hypothesis formation and testing until you reach a conclusion that is reinforced by supporting data or directly solves the problem at hand. In essence, Bacon thought thatinductive reasoning based on empirical observation was critical to the formulation of hypothesesand thegeneration of new understanding: general or universal principles describing how nature works are derived only from observations of recurring phenomena and data recorded from them.
