To paraphrase José Ortega Y Gasset, when we hear a unicorn, it is the unicorn that is present and evident, not our hearing it.  We do not hear our hearing when we are listening.  In order to realize that there is such a thing as our hearing, we have to stop listening and remember that a moment ago we were hearing.  We hear our hearing when we are outside it, when it is not immediate to us, when the reality with which it had to do -- hearing the unicorn -- is reality no longer, but rather we are in another reality which we call 'remembering a past event': recalling that we heard a unicorn.  To those who think that unicorns are not real, we reply that what we think is never reality; a thought doesn't and can't think itself -- a thought, far from being fundamental reality, is no more than an invention -- something hypothetical or theoretical.  To truly know unicorns, it is necessary to subtract all of that which has been thought, to realize that the reality of unicorns is always different from that which is thought.  In a nutshell, the pre-intellectual executive act consists in the coexistence of oneself with unicorns.
