Based on the review of academic activity of JAMS since its foundation
about 10 years ago, this presidential address advocates that activitie
s in mathematical sociology need not be based on a single orthodox phi
losophical basis. Activities in mathematical sociology are, and should
be, so various that the philosophy they base on as a whole should be
multifarious. Each project should adapt the philosophy that is most su
itable to its characteristics and abstraction level. The address also
stresses that mathematical sociologists should be interested in pursui
ng the mechanism of social reality rather than in the technical improv
ement of mathematical models.
