immanuel kant is by farrrrr the world's most precise philosopher... EVER! haha.. this text, like many philosophical texts out there... was really dry.. and um.. long. but there's definitely a reason why this one's regarded as one of the greatest philosophical pieces out there. so the book's premise in a nutshell... noone can argue FOR or AGAINST an afterlife/God. he also digs into the idea that our understanding of the world and our ideas are based not only on experience, but on a priori concept... it's worth a read, esp if you are the soul searching type..
