The temporal immortality of the soul of man, that is to say, its eternal survival also after death, is not only in no way guaranteed, but this assumption in the first place will not do for us what we always tried to make it do. Is a riddle solved by the fact that I survive forever? Is this eternal life not as enigmatic as our present one? The solution of the riddle of life in space and time lies space and time.
Wittgenstein argues that the concept of the soul's immortality, or its survival after death, is far from certain. He suggests that merely surviving eternally does not address the fundamental mysteries we face in life. The notion of eternal life does not resolve the complexities of existence; instead, it leaves us with questions equally puzzling as those we confront in our current reality.
He posits that the answers to life's riddles are rooted within the nature of space and time themselves. Instead of seeking solace in the idea of an everlasting soul, he encourages us to explore and understand the dimensions of our existence within the context of the physical world, asserting that true comprehension lies beyond the mere assumption of immortality.
