总觉得眼前的世界不真实？Miles 和 Lena 将带你拆解康德的《纯粹理性批判》，看懂大脑如何通过时空滤镜主动为自然界“立法”，让你在理性的疆界内找回生活的清醒与掌控感。
Meilleure citation de 康德：为世界戴上滤镜
我们能认识的，只是这套系统处理后的“现象”；而那个不依赖于我们、事物原本的样子，也就是他说的“物自体”，我们是永远无法触及的。

Foire aux questions
在康德之前，哲学家们普遍认为人类的认知必须符合客观事物。康德扭转了这一观点，提出不是心灵去符合事物，而是事物在符合我们的心灵。他认为人类并不是被动地接收世界，而是通过大脑预装的“操作系统”（先天的直观形式和知性范畴）主动为自然界“立法”。这意味着我们看到的现象世界是经过人类认知结构处理后的结果。
康德认为这个数学命题既是“先天”的，也是“综合”的。它是“先天”的，因为它具有普遍必然性，不依赖于具体的感官经验；它是“综合”的，是因为仅仅分析“7”和“5”的概念并不能直接得到“12”，这个等号代表了一次知识的跨越和增加。通过这个例子，康德证明了人类拥有既稳固可靠又能带来新发现的知识基础，从而反驳了休谟将因果律视为“习惯性联想”的怀疑论。
“物自体”（或称自在之物）是指不依赖于人的感知而独立存在的、事物原本的样子。康德认为，由于人类必须通过时间和空间这两个“先天感性直观形式”以及知性范畴来观察世界，我们所能认识的只能是经过这些“滤镜”处理后的“现象”。而那个没有被滤镜过滤过的、最真实的原型，超出了人类认知能力的边界，因此是不可触及的。
“二律背反”是指当人类理性试图超越经验边界去探讨宇宙起源、灵魂不朽或上帝存在等“物自体”问题时，会发现两种完全相反的结论在逻辑上都能自圆其说。康德借此提醒我们理性是有局限的，不要试图用科学工具去测量形而上学的领域。这启示我们要学会区分“知识”与“信念”，将无法证实的问题留给实践理性与道德信仰，从而在有限的认知范围内清醒、理性地生活。
