The Bible tells us to lean not unto our own understanding but to trust in the One who has infinite knowledge and wisdom. Sensory indulgence requires more faith because it asks you to put total belief in something you experience and may think is right. The Word of God. Satan comes masquerading as an Angel of light because he knows alot of us are led by our perceptions. Sensory indulgence doesn't build character, it breeds self-absorbtion.
Truth requires investigation and discipline.
Being totally led by your perceptions forces you to shun what is right and good and prefer instant gratification. Sensory indulgence requires a follower mentality. This is self-deception. The more we allow this kind of belief to go unchallenged means that the world is moving further and further away from recognizing truth. Thank God that he never changes and truth is always ever-present.
