In this article, I discuss a manuscript written by the Dutch natural philosopher and professor Petrus van Musschenbroek (1692-1761), entitled 'Advice on how the study of philosophy should be directed, read in the year 1730' ('Consilia de dirigendo Studio Philosophico. praelecta A degrees 1730'). I show how the text should be situated in the genre of rationes studii. I analyse the organisation of the manuscript, with special attention for the outline and order of the disciplines discussed by van Musschenbroek. I argue that Christian Wolff (1679-1754) is an important influence here. Next, I present van Musschenbroek's views on the propaedeutic role of the liberal arts and mathematics. Finally, I discuss van Musschenbroek's choice of authors (specifically in the sections dealing with physics) in relation to contemporary views on 'sects' in philosophy and eclecticism. This will allow me to provide a more nuanced view on van Musschenbroek's 'Newtonianism'.
