Lezinsky studied philosophy for eight years as a Jesuit, and then became a judge in legal cases against the Jesuits concerning estates.
He wrote a treatise entitled “The non-existence of God” and was later executed on charges of atheism. His trial has been criticized and is seen as a case of legalized religious murder in Poland.
On the basis of a public accusation, a trial at the front of the Sejm Commission was conducted.
There is a transcript of the proceedings in a Library of Kórnik, including a speech by the Grand Duchy of Lithuania Instigator Regni Szymon Kurowicz Zabistowski, in which he cited fragments of De non existentia Dei.
“After recantation the culprit was conducted to the scaffold, where the executioner tore with a burning iron the tongue and the mouth, with which he had been cruel against God; after which his hands, the instruments of the abominable production, were burnt at a slow fire, the sacrilegious paper was thrown into the flames; finally himself, that monster of his century, this deicide was thrown into the expiatory flames; expiatory if such a crime may be atoned for.”
The treatise itself was destroyed by the diet but the cited fragments that survived are as follows:
I – we beseech you, o’ theologians, by your God, if in this manner 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 him the impossible, the characteristics and attributes contradicting themselves.
II – the Man is a creator of God, and God is a concept and creation of a Man. Hence the people are architects and engineers of God and God is not a true being, but a being existing only within mind, being chimeric by its nature, because a God and a chimera are the same.
III – Religion was constituted by people without religion, so they could be worshipped although the God is not existent. Piety was introduced by the unpietic. The fear of God was spread by the unafraid so that the people were afraid of them in the end. Devotion named godly is a design of Man. Doctrine, be it logical or philosophical, bragging to be teaching the truth of God, is false, and on the contrary, the one condemned as false, is the very true one.
IV – simple folk are cheated by the more cunning with the fabrication of God for their own oppression; whereas the same oppression is shielded by the folk in a way, that if the wise attempted to free them by the truth, they would be quelled by the very people.
V – nevertheless we do not experience within us and within any other such an imperative of reason, which would ensure us of a truth of divine revelation. Alas if they were present in us, then everyone would have to acknowledge them and would have no doubts and would not contradict the Writings of Moses and the Gospels – which is not true – and there would be no different congregations and their followers as Mahomet etc. Such an imperative is not known and there are not only doubts, but there are some who deny a revelation, and they are not fools, but wise men, who with a proper reasoning prove what? the very contrary, what I also prove here. Concluding, that God does not exist”.
