We navigate the history of philosophy,focus mostly on the so called linguistic turn of modern philosophy.We will also retrospect the development of modern logic,especially the clarification of various concepts.We point out that modern logic and analytic philosophy have the same origin,and we argue that they still share the same fundamental methodology and even the same questions.We propose that philosophers should put more eyes on mathematical logic and mathematicians may do a better job when philosophical concern is borne in their mind.
