As modern-day neuroscience tells us, we are never in touch with the present, because neural information-processing itself takes time. Signals take time to travel from your sensory organs along the multiple neuronal pathways in your body to your brain, and they take time to be processed and transformed into objects, scenes, and complex situations. So, strictly speaking, what you are experiencing as the present moment is actually the past.

If we are capable of rejecting such offers or to postpone them into the future, then we can also concentrate on that which we currently want to do.
Thomas MetzingerA lot of evidence shows that most of our cognitive processing is unconscious - phenomenal experience is just a very small slice or partition of a much larger space in which mental processing takes place.
