When I see the blindness and the wretchedness of man, when I regard the whole silent universe and man without light, left to himself and, as it were, lost in this corner of the universe, without knowing who has put him there, what he has come to do, what will become of him at death, and incapable of all knowledge, I become terrified, like a man who should be carried in his sleep to a dreadful desert island and should awake without knowing where he is and without means of escape. And thereupon I wonder how people in a condition so wretched do not fall into despair. I see other persons around me of a like nature. I ask them if they are better informed than I am. They tell me that they are not. And thereupon these wretched and lost beings, having looked around them and seen some pleasing objects, have given and attached themselves to them. For my own part, I have not been able to attach myself to them, and, considering how strongly it appears that there is something else than what I see, I have examined whether this God has not left some sign of Himself.
I see many contradictory religions, and consequently all false save one. Each wants to be believed on its own authority, and threatens unbelievers. I do not therefore believe them. Every one can say this; every one can call himself a prophet.
But I see that Christian religion wherein prophecies are fulfilled; and that is what every one cannot do.
