The necessity of ordering the philosohpical path that leads Clarence
Irving Lewis to the formulation of the systems of strict implication
gives birth to this work of thesis. After a short general introduction
about the life and the philosophical view of Lewis, which is not
strictly related to the logical writings, the attention has been at first
focused on the historical-philosophic period between the nineteenth
and twentieth centuries the framework in which his logical studies
are put in, and afterwards on one of the first debates about material
implication which shows Bertrand Russell and Hugh MacColl
as leading actors. Subsequently an analysis of the early writings of
Lewis has been performed. This period started with Implication and
the Algebra of Logic, published in 1912, and ended in 1918 with Survey
of Symbolic Logic; and the subsequent revisions written in 1920
in the article A Strict Implication - An Emandation. For the first time,
the theory of the strict implication has been shown. Chapter three is
dedicated to the Symbolic Logic. This text is known as fundamental
in the history of Lewis’ thought. Particularly, the work has been interested
in a specific way to those chapters dedicated to truth-value
systems and to the notions of implication and deducibility, central
ideas in the Harvard’s philosopher logic system. Furthermore a section
has been dedicated to the analysis of the systems of strict implication:
S1, S2, S3, S4, S5, that represent the highest peak of the
Lewis’ logical study.
