The development of philosophy has always been intertwined with continuous disputes and crises. In the context where language analysis is highly regarded, the exploration of the meaning of speculative discourse manifests itself as a rejection of traditional ontology, accompanied by attempts to transform philosophy in the paradigm of natural science. Based on Wittgenstein's views on language philosophy, this paper attempts to demonstrate that it is neither possible nor appropriate to reject speculative philosophy from a scientistic stance. There is no philosophy without doubt, and Wittgenstein has fully embodied this belief. Especially in an era of the rapid development of natural science, Wittgenstein was able to demarcate the boundaries of scientific expression, point out the empirical essence of absolute concepts in ethics and the emptiness caused by the abuse of language. He paved the way for philosophy from the perspectives of thought and language, revealing meaning and value. All of this is closely related to his unique and thorough spirit of doubt.
