A Mathematical Proof of the Non-Existence of Hell from the writings of the free-thinker Neiht, born in Brussels, 1877. "The area of the valley of Jehoshaphat is 60,000,000 sq. ms. … Supposing that each race originated with one couple only, one has five couples or ten people, and applying to them the principle of compound interest, up to the Flood there were 9,289,000 births in 1,658 years. Since the Flood up to our epoch 2,326 years have passed, during which, if only five couples survived, they would have produced 2,213,867,610,000 children. If these calculations are extended up to the year 2000, the resulting number is 34,326,414,259,675,172,000 which, together with the 9,289,000, makes 34,326,414,259,684,461,000 offspring. If one concedes, charitably, that all papists are saved, their number today being 1/7th of the population of the earth, that of the damned would be made up of those born before the Flood plus those born since the Flood up to the year 2000 minus the 1/7th of those born since the year 44, that of the birth of Christ: this number is 4,903,773,008,164,544,000, and the total of damned would be 29,422,641,251,519,917,000.
The valley of Jehoshaphat is the Gehenna of the Jews (Jehennam in the Koran)–the place of eternal torment. The word is derived from Gehinnom = the valley of Hinnom where sacrifices were offered to Moloch (2 Corinthians 33 6) (= Adremmelech–the God of Sepharvaim). In later times, all manner of refuse was dumped there and fires were constantly maintained to consume it. The sulfurous stench and the fire was the original of the Christian concept of Hell. (The estimate of Nieht of Gehenna's area 60 × 10^6 sq. m. is wrong, according to measurements taken on the spot by the Editors).
