Whether the heavenly bodies are the cause of what is produced in bodies here below?

❌ Objection 1 : It would seem that the heavenly bodies are not the cause of what is produced in bodies here below. For Damascene says (De Fide Orth. ii, 7): "We say that they"---namely, the heavenly bodies---"are not the cause of generation or corruption: they are rather signs of storms and atmospheric changes."

❌ Objection 2 : Further, for the production of anything, an agent and matter suffice. But in things here below there is passive matter; and there are contrary agents---heat and cold, and the like. Therefore for the production of things here below, there is no need to ascribe causality to the heavenly bodies.

❌ Objection 3 : Further, the agent produces its like. Now it is to be observed that everything which is produced here below is produced through the action of heat and cold, moisture and dryness, and other such qualities, which do not exist in heavenly bodies. Therefore the heavenly bodies are not the cause of what is produced here below.

❌ Objection 4 : Further, Augustine says (De Civ. Dei v, 6): "Nothing is more corporeal than sex." But sex is not caused by the heavenly bodies: a sign of this is that of twins born under the same constellation, one may be male, the other female. Therefore the heavenly bodies are not the cause of things produced in bodies here below.
