We beseech you […] do you not extinguish the light of Reason, do you not oust the sun from this world, do you not pull down your God from the sky, when attributing to him the impossible.
Man is the creator of God, and God is a concept and creation of Man.
God is not existent.
Piety was introduced by the impious.
The fear of God was spread by the unafraid so that the people would be afraid of them in the end.
Simple folk are cheated by the more cunning with the fabrication of God for their own oppression.
— Kazimierz Łyszczyński, De non-existentia Dei, 1674
