The secular moral or secular moral philosophy is dealing with the morality independently of the religious traditions . It is opposed to religious morality and identification of religion as a source of morality, and the moral foundation of freethinkers and humanists , among others.
The theme of morality without religion is treated by both scholars and writers based in popular culture, including books and studies like The God Delusion (2006) by Richard Dawkins , The Science of Good and Evil (2004) by Michael Shermer , God Is Not Great (2007) by Christopher Hitchens , Can we be good without God (1996) Paul Chamberlain, or Godless Morality: Keeping religion out of ethics (1999) Richard Holloway.
Several figures of religious traditions have asserted that while the nonreligious can and do act morally, the idea of moral and abstract rules of good and evil can not exist without some kind of religious component. For example, scholar and writer CS Lewis made the argument in Mere Christianity (Mere Christianity) that if the supernatural and objective standard of good and evil does not exist outside of the natural world, then the concept of “good” and “bad” becomes stuck in the is-ought problem , why, preferences for a certain moral standard over another, is inherently unsustainable and arbitrary, as preferring a taste over another in a food, or choose one side or the other in One Way. 1
Some thinkers non – theistic , nihilistic and existential issues have pointed out that as good and evil have no meaning and any notion of morality is pure fantasy. The writer and philosopher Albert Camus , dominating theme of the indifference of the universe to humans and little sense of life in his novel The Stranger , in which the protagonist accept the death penalty without sadness or feelings of justice or morality.
