The idea of 'rationality' is still dominating in modern philosophical thinking. On one hand, there are philosophers who worship algorithms and formal structures of logical procedures. On the other hand there are those who tend to subjectivism, scepticism or relativism because of the impossibility to capture 'God's eye view' (as a remainder of 'rationality'). By substituting the concept of 'reasonableness' for the idea of the 'rational' Stephen Toulmin hopes to avoid the relativistic trap.
