  From the things considered above, it becomes clear that Zabarella cannot be considered as a precursor of modern experimental science. In spite of its empirical basis, Zabarella’s natural philosophy is not concerned with anything akin to experiment. Indeed, if experiments were to be developed, they would find their place in the productive arts rather than in natural philosophy. Zabarella did not use experiments in order to verify or falsify theories in the modern sense.  (Schmitt 1969) However, he made observations of natural things, but they were just made to exemplify and illustrate the demonstrative reasoning used in the theoretical natural philosophy (Rossi 1983, p. 146).
