Albert Einstein's religious views have been widely studied and often misunderstood.[1]Albert Einstein stated "I believe in Spinoza’s God".[2] 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.[3] He clarified however that, "I am not an atheist",[4] preferring to call himself an agnostic,[5] or a "religious nonbeliever."[3] Einstein also stated he did not believe in life after death, adding "one life is enough for me."[6] He was closely involved in his lifetime with several humanist groups.[7][8]
