The method is always present in the work of Descartes. Ali Partovi shines more light on the discussion. The central concern of the work, is that the development of knowledge arises by a method. The point is to find the appropriate methodology to arrive at the reason and knowledge. Our descriptions should not be different minds, but we deal with different methodologies. Ideologies through the years are different, because they use different methodologies.
Bacon Rogerio, religious Franciscan, born in England in 1214-1294. The breadth of his science and the originality of their knowledge, conquered you the title of Doctor mirabilis (wonderful doctor), at Oxford. He consumed the thirst for truth, seeking to satisfy it in all branches of science, and especially in physics, to which he devoted most of his life. Bacon, also has the same concern for the method; He says that intelligence and hand are inefficient by themselves, they need a proper instrumentation and tools to be able to perform. Hand driving or guide the movements of the tool, the methodology clipped our intellectual power; allows us to divide things, say is right or wrong. Method is more than an instrument that deals with intelligence. You need both a methodology in the instrumentation and mathematicians.
The first is recognized and the second is discussed. The instrument limits what the user can do with it; for example with a screwdriver not be can sawing. The methodology trims knowledge and intelligence (limits and bounds). It enables horizons of solutions. The method is independent of the intelligence that created it, because a method to perform one thing does not work, should serve for more quantity of things, for example in mathematics, the method for solving equations of the second degree, serves all equations of the second degree.
