Hobbes and Kant

Let us consider that we are witnesses to a man falling overboard from a ship. Excepting skeptical
quibbles about errors in sense perception, we have no difficulty in stating this sort of observation as
a fact. It is an observational fact but it is not a fact generated within the ambit of science. Hobbes
begins with acknowledging the fundamentality of sense observations, however, he continues to a
notion of science. Science takes empirical or sense observations in terms of a systematic framework
of concepts defined in words or symbols. Thus, the science of physics treats the man falling
overboard by a body falling a certain distance in a certain time, under certain qualifying constraints
like wind resistance; physiology treats say the action of the lungs when a person of a certain age
and condition falls a distance; psychology may treat this matter as a suicide. Each science or
conceptual frame is warranted by rigorous definitions of its concepts in a particular convenient
language. Consequently, the rigor of physics compared to psychology has a greater warrant to be a
science.
