The Inner levels of their mind, levels that see in heaven’s light, are closed to the point where they see nothing true related to heaven or the church. Their thinking occurs on an outermost level and not inside, where the light is spiritual. Since the light they have is dull and earthly, people like this are inwardly opposed to things related to heaven and the church, although
they are outwardly able to speak in favor of them. If they have hope of gaining ruling power or wealth by so doing, they are even capable of speaking ardently in favor of them.
The educated and the scholarly who are deeply convinced of falsities–especially people who oppose the truths in the Word–are more sense-oriented than others.
Sense-oriented people are able to reason shapely and skillfully, because their thinking is so close to their speech as to be practically in it–almost inside their lips; and also because they attribute all intelligence solely to the ability to speak from memory. They also have great skill at defending things that are false. After they have defended falsities convincingly, they themselves believe those falsities are true. They base their reasoning and defense on mistaken impressions from the senses that the public finds captivating and convincing.
