Rational is arrived at by the use of the peculiarly human mental processes by which man strives to connect his ideas as consciously, coherently and purposively as possible in order to plan the attainment of ends sought. In view of the human fallibility in selecting the best possible reasoning for attaining the ends sought, there is no implication as to the correctness or incorrectness of the reasoning. Consequently, all conscious human actions, whether or not appropriate for the ends sought, are rational.
