What is Science 2
On the other hand, deductions in rationalism in Western
Knowledge make use of rules of inference, which are obtained through induction.
The rule if a=c and b=c, then a=b is nothing but a
generalization from limited observations such as if two people are equal in
height to a third person, then the two people concerned are themselves equal in
height to one another. The rule if a=b then b=a, or the
rule a=a are rules of inference obtained through induction by observing
a limited number of cases. These rules are not God given. Reasoning which
depends on rules of inference, obtained by induction cannot be justified
without induction that does not come under logic.
