Whether the cause assigned for the production of the lights is reasonable?

❌ Objection 1 : It would seem that the cause assigned for the production of the lights is not reasonable. For it is said (Jer. 10:2): "Be not afraid of the signs of heaven, which the heathens fear." Therefore the heavenly lights were not made to be signs.

❌ Objection 2 : Further, sign is contradistinguished from cause. But the lights are the cause of what takes place upon the earth. Therefore they are not signs.

❌ Objection 3 : Further, the distinction of seasons and days began from the first day. Therefore the lights were not made "for seasons, and days, and years," that is, in order to distinguish them.

❌ Objection 4 : Further, nothing is made for the sake of that which is inferior to itself, "since the end is better than the means" (Topic. iii). But the lights are nobler than the earth. Therefore they were not made "to enlighten it."

❌ Objection 5 : Further, the new moon cannot be said "to rule the night." But such it probably did when first made; for men begin to count from the new moon. The moon, therefore, was not made "to rule the night."
