I wonder if you have visited George F. Spencer's monument in the Lyndon Center cemetery. He died in 1908. It's definitely worth seeking out.
It's a large limestone monument with a sleeping babe on top. It stands in the first row on the right next to to the central, east-west road. This is the epitaph (it was partially defaced after his burial):
Beyond the universe there is nothing and within the universe the supernatural does not and cannot exist.* Of all deceivers who have plagued mankind, none are so deeply ruinous to human happiness as those imposters who pretend to lead by a light above nature.
Science has never killed or persecuted a single person for doubting or denying its teachings, and most of those teachings have been true; but religion has murdered millions for doubting or denying her dogmas, and most of those dogmas have been false.
All stories about gods and devils, of heavens and hells, as they do not conform to nature and are not apparent to sense, should be rejected without consideration.
The lips of the dead are closed forever. There comes no voice from the tomb, Christianity is responsible for having cast the fable of eternal fire over almost every grave.
