"Two types of intellect exist: 1. The commonly known sensual intellect. 2. The intellect which is given by the Being; this is a conscious intellect." - Samael Aun Weor, The Revolution of the Dialectic
The common sensual or subjective intellect is the capacity of reasoning and comparing (see Intellectual Animal). Related to the Intellectual Brain or Center, and to the physical brain.
"The intellect is a very precious instrument for the Great Work of the Father, when it is absolutely used for the pure service of the Spirit. A mystic without intellect fails because of lack of culture (see Intellectual Culture). The intellect is satanic when it is used for the service of the internal beast. The intellectual villains (cynics and skeptics) are the result of intellectualism without spirituality." - Samael Aun Weor, The Aquarian Message
"The intellect never attains Initiation. Only the heart attains the Golgotha of the High Initiation. The majority of people have their heads filled with absurd theories and ancestral prejudices; they do not open their minds to anything new." - Samael Aun Weor, The Revolution of Beelzebub
