  Despite the success of modern physics in formulating mathematical theories
that can predict the outcome of quantum-scale experiments, the physical
interpretations of these theories remain controversial. In this manuscript, we
propose a new interpretation of existence that we call physical relativism.
Under physical relativism, the difference between mathematical existence and
physical existence is clarified, and Wheeler's `it from bit' viewpoint can be
objectively evaluated. In addition, physical relativism provides a simple
answer to the question of why the universe exists at all, and permits us to
derive the maximally biophilic principle, a generalization of the anthropic
principle that ascribes high prior likelihood to the observation of a universe
with simple physical laws supporting the overall concepts of time, space and
the emergent evolution of life.
