It is on such observations that the actuary founds his estimates of the mortality that exists at any given period of life.

The actuary tells you that he has been guided by the Laws of Mortality.

Now the results must be very regular, to justify the actuary in speaking of Mortality as governed by Laws.

And yet it is so.
Indeed, there would seem to be no such thing as chance in the world.

Man lives and dies in conformity to a law.
