Vision and Mission

Our vision is of a society where reason and evidence guide individual and civic principles, and where none suffer prejudice for a commitment to rationality. Our mission is to nurture a community in the Miami Valley that values secular humanism, promotes and preserves freethought in the public square, provides supportive fellowship, and engages in humanitarian good works.

Quote of the Day by John Bremner

Proof of the non-existence of GodTo most believers god is omniscient and omnipotent. However, there are a few problems with this view that are difficult to surmount. If god is omniscient – all knowing, all seeing, then by definition he knows everything there is to know, past, present and future. By definition, therefore, he cannot learn anything, because to learn something would imply that he did not already know that thing. However, a god who cannot learn is not omnipotent – all powerful, because there is something that he cannot do. If on the other hand, God is capable of learning, he cannot be omniscient, because by definition there must be something that he does not know. Therefore god is not both omnipotent and omniscient. However, this does not necessarily mean that he is not one of these things. A closer look at these arguments though, makes it clear that omnipotence includes omniscience – an all powerful god is a god capable of doing anything including knowing things. However, since it has already been established that both qualities cannot coexist in god, there is no omnipotent god.Let P represent omnipotence.Let O represent omniscienceIf P exists, it must include O.P does not include O therefore P does not exist. This leaves only the possibility of God being omniscient. However, A closer look at these arguments again, makes it clear that omniscience includes omnipotence, because an omniscient god is a god that knows everything, including how to make anything happen. However, since it has already been established that both qualities cannot coexist in god, there is no omniscient god.If O exists, it must includes P.O does not include P therefore O does not exist.Hence there is neither an omnipotent god or an omniscient god, and anyone who believes in any current version of God is wrong. – John Bremner

Quote of the Day by 8 Track Mind

i like it when baseball players hit a home run and point their index finger up in the air and look up with their heads. I have never figured out why when they strike out they don’t look up and raise a different finger. – 8 Track Mind

Quote of the Day by Roy Zimmerman

And it began to rain toads and fire and he brought seven plagues. Jesus would not preach hate, Jesus would not stand in rubble and say I told you so, Jesus would not use an international catastrophe to score points for some narrow misogynistic antis emetic homophobic interpretations of his life and teachings. And if people are vengeful, jealous and violent maybe is because YOU created them in YOUR image – Roy Zimmerman
