Why reflect on creation? Answer: because God made everything to reflect himself—and he is our beatitude. So pursue medicine, arts, nature, and crafts for the sake of happiness, eudaimonia, makarios, or whatever term you prefer.
Human culture can cultivate the goodness of creation which itself shares in the goodness of God. Or it can vitiate what is good and descend into non-being.
One promises beatitude; the other non-being.
So build well. Love what you create. Enjoy God’s gifts.
