Aspects of Aristotelianism in the Early Thought of Galileo Galilei

It is well known that Aristotle’s Analytica posteriora is the predominant point of reference for all the scientific methodology from the thirteenth to the seventeenth century, that is, until the advent of modern science. During this time science has entered a new era, in which there is the need to base scientific research on a shared method. Galileo Galilei composes his first three latin manuscripts in the years in which he teaches at the University of Pisa, in the period between 1589 and 1591. The first of these is undoubtedly the ms. 27 which contains a synthesis and an elaboration of traditional logical and methodological discussion of the sixteenth century, focusing on Aristotle's Posterior Analytics.
