“The Inner Truth” explores the concept of spirituality from the perspective of
the human mind. The chapter starts with a basic introduction to the theory of neurons
and neurotransmitters and then explains how they work by using the theory of artificial
neural networks as a mathematical analogy. It reveals that, if the theory of artificial
neural networks is an acceptable model of the brain, then the human mind cannot
arbitrarily create any idea that it wants to; ideas are apparently created from
preconceived thinking patterns that were learned by trial and error in the past. The
discussion then provides a quick introduction to statistics. It explains that statistics can
be used as a tool to measure ambiguous human concepts such as words and feelings. It
concludes that, if the theory of evolution is correct, then the brain may contain a
spiritual inner truth that explains why so many scientists today do not see any conflicts
between science and spirituality.
