The current post will not conclusively answer if souls exist
or not. What it will definitely do is develop a scientific line of inquiry that
may lead to an answer about the existence of souls. But before that, what do we
mean by a soul? Google it and this is what Wikipedia has to say – “A soul – in
certain spiritual, philosophical, and psychological traditions – is the
incorporeal essence of a person, living thing, or object”. The catch here is
that the soul, if it exists, is incorporeal, not matter.
All possible efforts shall be made to argue with in the realms
of reason and not resort to scriptural dogmatism. Since we are discussing the
question of existence, let’s see what can possibly be valid proofs of some
object’s existence. We will start with some very obvious objects/phenomena/property.
Take the sun. We know that it exists, because we can directly perceive it
(through our faculty of vision). Another example – sound waves exist because we
can directly perceive them (through our faculty of hearing).
Let’s complicate a little. The nucleus of an atom – Direct
perception is not possible here, courtesy the limitation of our vision. What do
we do now? We perform Rutherford’s alpha rays scattering experiment and infer
that an atom has something called the ‘nucleus’. The spin of an electron,
wave-particle duality, electricity, magnetism are other examples where our
senses fail us in direct perception. The more we move away from the limited
sphere covered by our senses, the greater is the need for inferential
arguments.
The point of the above discussion is this – if direct
perception fails us in distinguishing certain states of matter, then it will
surely fail in that which is immaterial/ incorporeal- a soul. So we have to
cook up an inferential inquiry. If there is a soul in humans, then an
individual can be thought of to have three parts – the physical body, the brain
and a soul. If we can somehow ‘switch off’ the physiological body and the
brain, whatever remains will provide an answer about the soul’s existence. This
is no ingenious technique – this is exactly what you’d do if your house’s
electrical wiring goes awry – check each wire one by one after switching off
the rest.
It is no easy task to switch off our physiological and mental
components (I, for one, prefer agnosticism in this regard) How do we control
the heart, or our digestive system? And that’s only half the story. The brain
is even queerer. It doesn’t stop for one moment. You might think that it does
when you sleep – but it doesn’t. Here is a simple explanation – if the brain
does stop when you are asleep, how is it that dreams are registered? The brain
never stops.
To sum up, because we do not directly perceive the soul cannot be a reason
to deny its existence. Advice on how to control the physical and the mental
might provide an answer to the soul’s existence. The system of Yoga addresses
this need.
