The first knowledge that a man acquires is through instinct—reason enters at a later stage, its primary role is to analyze and confirm the knowledge which instinct has acquired. The idea of supremacy of reason which the modern philosophers preach is illusory. Reason is not superior to instinct; both play an equally important role for acquiring knowledge. The modern era is not only an age of reason but also an age of instinct. The proficiency in the use of reason is the mark of a technical man; the proficiency in the use of instinct is the mark of a wise man. Progress happens when technical knowledge and wisdom march hand in hand.
