“Grosseteste most often features in accounts of medieval thought because of his contribution to the scientific method, and for what has been called his ‘metaphysics of light’. Although Grosseteste spoke, in his commentary on the Posterior Analytics, on how to reach a universal principle based on experience (principium universale experimentale), the claim sometime made that he, first in the Middle Ages, devised an experimental method is borne out neither by his theoretical nor his more practical scientific works. The main achievement of Grosseteste’s widely-read commentary was, rather, to help put into circulation the ideas of the Aristotelian treatise which did not guide scientific investigation in the modern sense, but helped rather in thinking about the organization of knowledge.”
