Albert Einstein's religious views have been widely studied and often misunderstood. Albert Einstein stated "I believe in Spinoza's God". He did not believe in a personal God who concerns himself with fates and actions of human beings, a view which he described as naïve. He clarified however that, "I am not an atheist", preferring to call himself an agnostic, or a "religious nonbeliever." In other interviews, he stated that he thought that there is a "lawgiver" who sets the laws of the universe. Einstein also stated he did not believe in life after death, adding "one life is enough for me." He was closely involved in his lifetime with several humanist groups. Einstein rejected a conflict between science and religion, and held that cosmic religion was necessary for science.
