Philosophy is the enquiry of wisdom and the question of human nation and way of heaven, in the view of substantive lev- el. It can be understood as the process of concept＇s usage with the perspective of form level. If we turn our direction from wisdom search in narrow sense to wisdom thinking in board sense, then we can integrate philosophical idea as opinion in our inquiry of philosophy. In this sense, the philosophy as wisdom thinking can include the philosophy as opinion. At the same time, it is needed to differentiate the conclusion of philosophy and the last word of philosophy. Philosophy needs conclusion, but it does not mean final conclusion. In general, final conclusion can only be accepted, not for suspicion and discussion. But the conclusion of philosophy can be put in the academic community for critical thinking. Different answers to philosophy are related to different philosophical approaches and philosophers＂ personalities. Essentially, philosophy per se is the personalized pursuit of wisdom.
