Aristotle held the belief that man is a rational animal. A growing body of research suggests otherwise.
Rational: of or based on reasoning (from Webster’s New World Dictionary). This ambiguous definition is similar to what is given by many people when asked to define rational. This type of definition is virtually worthless as it becomes open to a plethora of interpretations. In order to teach and express the importance of rational thinking it is imperative to precisely define the concept.
What is rationality?
Rationality is concerned with two key things: what is true and what to do (Manktelow, 2004). In order for our beliefs to be rational they must be in agreement with evidence. In order for our actions to be rational they must be conducive to obtaining our goals.
