Name: Atheism & Secular Humanism
Worldview category: Atheism
Symbol: Atheism has no official symbol. However, it is frequently represented by the letter “A” surrounded by several revolving atoms (as shown above) and on bumper stickers by the word “Darwin” inside the outline of a fish with legs and feet (which represent evolution). The symbol parodies the fish symbol, which is used in Christianity.
Atheism – The belief that neither God nor gods exist. Atheism holds to the belief that the physical world is all that exists. Atheism denies the existence of the supernatural world. Since God does not exist, man is in control of his own destiny and creates his own meaning in life. Observation, experience, logic, and reason are the foundations of knowledge and understanding.
Secular humanism - "The belief that humanity is the highest of all beings and truth and knowledge rest in science and human reason." 
"Humanism is a progressive philosophy of life that, without supernaturalism, affirms our ability and responsibility to lead ethical lives of personal fulfillment that aspire to the greater good of humanity."
