Carl Friedrich von Weizsäcker's concept of time is deeply based on the asymmetry between past and future, which he considers as a fundamental aspect of Nature. I review these ideas and their philosophical back ground and confront them with a presentation of the concept of time in modern physics. I argue that the observed irreversibility of our world can be understood from fundamental laws which are invariant under time reversal. I conclude with an outlook on the expected theory of quantum gravity.
卡尔·弗里德里希·冯·魏茨泽克的时间概念深深基于过去与未来之间的不对称性，他将这种不对称性视为自然的一个基本方面。我回顾这些观点及其哲学背景，并将它们与现代物理学中的时间概念呈现进行对比。我认为，我们世界中观察到的不可逆性可以从时间反演不变的基本定律中得到理解。最后，我展望了量子引力的预期理论。
