"This term *unknowable* - I think it applies to the mysteries of life, like love and peace and death, and life itself. These are things we can experience, but we will never fully understand them. These mysteries are the realm of religious thought."

These subjects I would call knowable, and scientifically explicable too because natural selection and evolution probably play a major part in explaining them all. We are the way we are because characteristics have been selected as advantageous for our current environment, and our inability to avoid physical conflict and even death are explicable in the physical sense, and I'm not aware a jot of empirical evidence that suggests otherwise.
