Who is this David Wilcock guy?

What makes you believe the heart cannot discern without intellect? I ask out of pure curiosity, not in an accusatory manner (which that can be interpreted as).

Well it certainly can on it's own, however it seems analytical skills allow one to analyse and process such data in relation to the experience in a more efficient manner, which may not have been the case otherwise. One may 'feel' discomfort whilst locked to a certain paradigm for example (Fundamentalist abrahamic religion, say), however may lack the necessary skill to critically analyse the genesis of the emotions and make the connection between mindlessly practising that which had been conditioned, and acknowledging catalyst in order to make conscious that which may not necessarily have been so prior.

There is a supporting statement in the Ra material as well:

Ra: I am Ra. The lobes of your physical complex brain are alike in their use of weak electrical energy. The entity ruled by intuition and impulse is equal to the entity governed by rational analysis when polarity is considered. The lobes may both be used for service to self or service to others. It may seem that the rational or analytical mind might have more of a possibility of successfully pursuing the negative orientation due to the fact that, in our understanding, too much order is by its essence negative. However, this same ability to structure abstract concepts and to analyze experiential data may be the key to rapid positive polarization. It may be said that those whose analytical capacities are predominant have somewhat more to work with in polarizing.
