Reason and ethos: Consequences of their separation and necessity of their unity

Although the concept of "reason" acquired a precise meaning and clearly defined field of validity only in Kant's critical philosophy, the term has a long genesis in European intellectual history. The roots of the concept lie in the Greek concept of the logos and may be reduced to six basic meanings. The earliest Greek thinkers used the word logos to denote the logical structure of the human thought and the rational structure of the world. Anaxagoras considered the all-embracing spiritual principle of the nous the source of overall rationality. In the philosophy of the Stoa the term - logos spermaticos is the active principle acting on passive matter in order to create the world. For the Stoics, the concept of logos is the fundamental principle of entire morality. In Christian theology, the God is logos, Holy Spirit - pneuma the soul. In modern philosophy the basic meanings of the Greek logos were taken over by Latin terms "intellectus" and "ratio". These concepts chart quite clearly two basic lines of European thought, one characterized by immediate and the other by mediated discursive understanding of the truth. Kant was the first in the history of philosophy to introduce the essential distinction between understanding and reason (Verstand and Vernunft). According to this distinction, understanding is analytical and abstract, while reason is the source of apriori principles connecting and grounding the whole of our knowledge and volition. Therefore Kant distinguishes theoretical from practical reason. Though practical reason applies the concepts and principles of theoretical reason, it has priority over the latter because it bestows practical reality also on what is theoretically unknowable (freedom, God, immortality of the soul). The primacy of practical reason was especially emphasized by Fichte in his Doctrine of Science. Reason is for him a purely purposeful activity. The idea of reason attains full articulation in Hegel's philosophy of the absolute spirit. For Hegel, reason is first of all a world principle rather than a human capacity. Unlike Kant, whose reason is basically static, a substantial novelty of Hegel's conception of the objective reason is its dynamism, enabling it to reach an increasing awareness "of itself" in its dialectical development. By including the idea of progress in his conception of reason, Hegel introduced an evaluative element in the concept of rationality and thus enabled a connection between reason and ethos in the era of modernity. The deepest cleavage between reason and ethos was opened by the modern science. On one
