I read this in the latest Brain Picking. David Bohm is a theoretical physicist.
“Reality is what we take to be true. What we take to be true is what we believe. What we believe is based upon our perceptions. What we perceive depends on what we look for. What we look for depends on what we think. What we think depends on what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. What we take to be true is our reality.”
I think theoretical science is really philosophy with maths.
