Do we even need our brains ? – Some Scientists aren’t so sure

Once during a discussion, a respectable someone (who I won’t name) suggested to me: “I believe the seat of the self is the heart. Not the brain!. I laugh at these scientific notions stating consciousness is in the brain. I believe in the future scientists will also accept the true seat of the self is in the heart..” He went as far as suggesting we ‘think’ with the heart as well.
