Translation:

 - I. The method of <A HREF="https://en.wikipedia.org/wiki/Cournot_competition">functional division,</A> proposed by the respectable <A HREF="https://en.wikipedia.org/wiki/Antoine_Augustin_Cournot">Cournot</A> as an analytical and empirical method, appears unsuitable, since one does not have fully empirical functions.
 - II. The method of the infinitely-small is, I claim, no less
   precise than the method of limits. 
 - III. It is of greater interest to
   investigate the implicit properties of a function defined by a
   differential equation than to investigate in terms of which known
   functions it can be expressed. 
 - IV. The principles of Democritus
   remain to the present day as the foundation of the theory of atoms.
