The first altar mentioned in the Word was the one built by Noah after he came out of the ark, after being saved from the great flood. On that altar, he sacrificed clean animals to the Lord.

Mountains represent the Lord because of their height; we need to raise our thoughts above worldly things when "talking" with the Lord. An altar is a small artificial mountain. When it's used in worship, it can call to mind this raising of thought. The fire and smoke that rise from an altar are symbolically being sent to the Lord.

Most altars were made from unhewn stones. Stones represent truths. Unhewn stones - ones that have not been shaped by men - represent truths from the Word, truths that have not been adulterated.

The clean beasts to be sacrificed represent good things, charitable acts done because they are right. The clean birds represent thoughts about doctrine and actions, and about what is right. Presenting these things is an acknowledgment that we have them from the Lord, and a giving thanks to Him for them.

In the Israelitish Tabernacle, the altar of burnt offering represented the acknowledgment of good and the altar of incense that of truth. For this reason this larger altar, which was outside by the door, was made of brass which signifies natural good, while the altar of incense was made of gold, which signifies love to the Lord from whom comes truth.

50. The sense-oriented people mentioned in the teachings in §45 above, who are the lowest of the earthly. The sensory level is the outermost limit of our life, attached to and embedded in our bodies: 5077, 5767, 9212, 9216, 9331, 9730. We call people sense-oriented who pass final judgment on everything on the basis of their physical senses and who do not believe in anything unless they can see it with their own eyes and touch it with their own hands, saying that only such a thing actually is something and rejecting everything else: 5094, 7693. People like this think on the outermost level and not more deeply within themselves: 5089, 5094, 6564, 7693. Their deeper levels are closed so that they do not see any bit of truth there: 6564, 6844, 6845. In short, they are in a crude earthly light and perceive nothing in heaven's light: 6201, 6310, 6564, 6598, 6844, 6845, 6612, 6614, 6622, 6624. They are therefore inwardly opposed to everything having to do with heaven and the church: 6201, 6316, 6844, 6845, 6948, 6949. Scholars who are adamantly opposed to the truths of the church are sense-oriented: 6316.

[2] Sense-oriented people are able to dispute with cleverness and with vehement certainty because their thinking is closely enmeshed with their speaking, and because, as they see it, intelligence in its entirety consists of words assembled solely out of facts recalled from the memory: 195, 196, 5700, 10236. The reasons they offer in their disputes, however, are based on deceptive sense impressions, which they use to ensnare ordinary people: 5084, 6948, 6949, 7693.

[3] Sense-oriented people are more shrewd and vicious than others: 7693, 10236. Misers, adulterers, hedonists, and deceivers are especially sense-oriented: 6310. Their deeper levels are befouled and filthy: 6201. They are in touch with hell through those levels: 6310. The people in the hells are sense-oriented, more and more so the deeper in hell they are: 4623, 6311. The aura of hellish spirits is joined to our sensory level from behind us: 6312. The ancients called people who reason on the basis of their senses and therefore against the truths that belong to religious faith "serpents of the tree of knowledge": 195, 196, 197, 6398, 6949, 10313.

[4] Further description of our sensory level and sense-oriented people (10236) and of the extension of our senses (9731).

[5] [Thoughts and desires] based on our senses should be put last, not first. In the wise and intelligent they are put last and are subject to the inner self. In those who are not wise, though, they are put first and are in control. These are the people who are properly called "sense-oriented": 5077, 5125, 5128, 7645. If a sensory perspective is put last and is subject to our inner self, a path to the understanding is opened through it and truths are refined from it by means of a kind of distillation: 5580.

[6] Our sensory functions are most directly exposed to the world; they let in things that enter from the world and filter them: 9726. Through these sensory functions our outer or earthly self is in touch with the world; through rational faculties it is in touch with heaven: 4009. In this way our sensory functions provide things that are useful to our deeper functions: 5077, 5081. Some of our senses support our understanding and others support our will: 5077.

[7] Unless our thinking is lifted out of sensory concerns we have little wisdom: 5089. Wise people think on a level higher than that of the senses: 5089, 5094. When our thinking rises above sensory concerns we come into a clearer light and eventually into a heavenly light: 6183, 6313, 6315, 9407, 9730, 9922. The ancients knew that it was desirable to rise above sensory concerns and be released from them: 6313. In our spirit we can see things that are in the spiritual world if we can be released from the sensory concerns that arise from our bodies and be lifted into heaven's light by the Lord: 4622. This is because it is not the body that is conscious but the spirit within the body, and to the extent that it is in the body the spirit's consciousness is coarse and cloudy and therefore in darkness. To the extent that it is not in the body, the spirit's consciousness is clear and is in the light: 4622, 6614, 6622.

Facts derived from the senses are the lowest level of our understanding, and sensory gratification is the lowest level of our will: 9996 (which includes discussion). The difference between the sensory functions we have in common with animals and the sensory functions we do not have in common with them: 10236. There are sense-oriented people who are not evil because their deeper levels are not completely closed. On their state in the other life: 6311.
