《实践理性批判》，该书出版于1788年，是康德思想的核心部分。《判断力批判》是《纯粹理性批判》和《实践理性批判》的中间环节。康德扮演的是基督教真理的维护者，是他首次确定了精神的永存和上帝的存在。书中讨论了生活中的至善问题，康德认为人在绝对服从道德律令的情况下，不应该只是去寻找快乐，而应该去寻找上帝赐予我们的幸福。

《实践理性批判》是德国古典哲学的开创者康德的“三大批判”著作中的第二部，也称“第二批判”。第二批判研究人类的意志能力，探讨道德法则是否能够成为意志的决定根据，如果能够，那么实践理性就是可能的，这同时也就证明了自由的可能性。在《实践理性批判》中，康德分别从实践理性的基本原理、实践理性的对象、实践理性的动力、实践理性的实现以及实践理性的公设等方面探讨了上述问题。
