Sed videtur definienda, ut sit, Habitus mentibus humanis a Deo cocessus, industria et exercitio auctus, quo comprehenduntur omnia quae sunt, qua certo & firma ratione comprehendi possunt, ut ad felicitatem homo perveniat. (Commentaria D. Petri Martyris Vermilii … in Primum librum Ethicorum Nicomachiorum Aristotelis)
So it appears that it [Philosophy] must be defined as a Habit given by God to the minds of man, increased by diligence and performance, by which all things which exist are known, able to be understood by certain and firm reason, so that man may attain happiness.
Like Aristotle, Vermigli believed that philosophy was for the purpose of achieving happiness in this life, not purely for the inventions of the speculative intellect. Therefore, philosophy is inherently practical. That is one reason why Reformed Divines on the continent and beyond emphasized the teachings of Aristotle in their local Gymnasia.
