Classically, the metrics of physics and the metrics of mathematical logic have been used to probe human experience. However, the problem have been taken for ‘reality’ and variations in response of these probes have been called illusions, errors or biases. But maybe these variations simply indicate that the phenomenon of experience requires different metrics than those used in physics or mathematical logic. The challenge is to discover the intrinsic dimensions and metrics of experience. If the goal is a science of experience, then we can’t start by denying the reality of that experience.
