Abstract

The paper aims at analyzing Lambert’s conception of empirical knowledge that is part of scientific learning. Indeed, in the Neues Organon, he claims that science is obtained with the help of both a priori and a posteriori knowledge. Lambert’s originality lies on the application of the analytic and synthetic methods of reasoning, which are traditionally used in formal disciplines, to the realm of experience. Transforming common knowledge into scientific a posteriori knowledge is mainly based on the employment of such demonstrative methods. This allows Lambert to introduce some important theoretical tools in his theory of experience, in particular about the search for the conditions of observations and experimentations as well as the establishment of hypothesis. For Lambert, the synthetic method in empirical deductions requires the use of conjectures and probable principles.
