實踐哲學的相關問題是國內外學界近些年所關注的一個熱門話題。然而對這個問題的討論囿于傳統精神-物質、理論-實踐式的二元思維方式的影響,總是從理論本身的變動方面展開,較少突破其局限而上升到元實踐哲學層面的追問,也即哲學之實踐轉向所蘊含的思維本身的實踐維度得以可能的內在機理及其意義為何沒有得到闡釋與辯護。鑒于此,本文以實用主義哲學為參照,通過對指號、意義、概念、判斷與思維之間關系的實踐性闡釋,闡明哲學思維從傳統思辨性的邏輯模式向實踐探究性的邏輯模式轉向的路徑及意義。

Questions on practice philosophy have been a hot topic of late,but discussions are limited by dualism—the way of thinking that fixates on mind-vs-matter,and theory-vs-practice. These discussions often focus on theoretical shifts rather than on inquiries into meta-practice philosophy—that is,the questions implied in the so-called "return"of practical philosophy,about why thinking must have a practical dimension,and the meaning of this return have not been elucidated or defended. Thus,this essay aims to inquire into these questions by discussing the relations between sign,meaning,concept,and thinking in light of practice,and explains its effects.
