WIKEPEDIA says , Reasoning is the cognitive process of looking for reasons, beliefs, conclusions, actions or feelings.Ya, its true, not going much into what reasoning is , what is more important is how to achieve this capability,how you can interpret different situations and problems and apply your thoughts and skills to get the most suitable inference.
