I am against religion because it teaches us to be satisfied with not understanding the world.
To sum up:
1. The cosmos is a gigantic flywheel making 10,000 revolutions a minute.
2. Man is a sick fly taking a dizzy ride on it.
3. Religion is the theory that the wheel was designed and set spinning to give him a ride.
H. L. Mencken
I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.
I do not believe in the creed professed by the Jewish Church, by the Roman Church, by the Greek Church, by the Turkish (Muslim) Church, by the Protestant Church, nor by any Church that I know of. My own mind is my own Church.
It's an incredible con job when you think about it, to believe something now in exchange for something after death. Even corporations with their reward systems don't try to make it posthumous.
Hast thou reason? I have.
Why then dost not thou use it?
For if this does its own work,
what else dost thou wish?
The sciences are not sectarian. People do not persecute each other on account of disagreements in mathematics. Families are not divided about botany and astronomy does not even tend to make a man hate his father and mother. It is what people do not know that they persecute each other about. Science will bring, not a sword, but peace.
Robert G. Ingersoll
Fundamentalism isn't about religion. It's about power.
I don't believe in God because I don't believe in Mother Goose.
For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
