Along with PET scans and EEGs, do you think the progress in math, Einstein's theories, and quantum physics in which we could now prove what we can not see, helped to move cognitive psychology into the realm of science and away from philosophy?
In some ways science helps to prove what we cannot see, but in some ways it has not, or may not provide evidence for the super natural. How can thoughts be measured?

I think human beings are immensely limited by what they cannot perceive through sensory systems. Along with PET scans, EEGs, mathematics, Einstein's theories, and the magnificent world of quantum physics, cognitive psychology will continue moving more into the realm of science [with its roots forever grounded in the field philosophy].
One may wonder: Philosophy has its own concentration; why does ...
