humanist ethics evolved to support secularism, civil rights, personal autonomy, religious toleration, multiculturalism, and cosmopolitanism. A naturalistic criticism of humanistic morality is the denial of the existence of morality. For naturalistic skeptics, morality was not hardwired within humans during their evolution; humans are primarily selfish and self-centered. Defending humanist morality, humanist philosopher John R. Shook makes three observations that lead him to the acceptance of morality. According to Shook, homo sapiens has a concept of morality that must have been with the species since the beginning of human history, developing by recognizing and thinking upon behaviors. He adds morality is universal among human cultures and all cultures strive to improve their moral level. Shook concludes while morality was initially generated by our genes, culture shaped human morals and continues to do so. He calls "moral naturalism" the view morality is a natural phenomenon, can be scientifically studied, and is a tool rather than a set of doctrines that was used to develop human culture. Humanist philosopher Brian Ellis advocates a social humanist theory of morality called "social contractual utilitarianism", which is based on Hume's naturalism and empathy, Aristotelian virtue theory, and Kant's idealism. According to Ellis, morality should aim for eudaimonia, an Aristotelian concept that combines a satisfying life with virtue and happiness by improving societies worldwide. Humanist Andrew Copson takes a consequentialist and utilitarian approach to morality; according to Copson, all humanist ethical traits aim at human welfare. Philosopher Stephen Law emphasizes some principles of humanist ethics; respect for personal moral autonomy, rejection of god-given moral commands, an aim for human well-being, and "emphasiz[ing] the role of reason in making moral judgements". Humanism's godless approach to morality has driven criticism from religious commentators. The necessity for a divine being delivering sets of doctrines for morals to exist is a common argument; according to Dostoevsky in The Brothers Karamazov; "if God does not exist, then everything is permitted". This argument suggests chaos will ensue if religious belief disappears. For humanists, theism is an obstacle to morality rather than a prerequisite for it. According to humanists, acting only out of fear, adherence to dogma, and expectation of a reward is a selfish motivation rather than morality. Humanists point to the subjectivity of the supposedly objective divine commands by referring to the Euthyphro dilemma; "does God command something because it is good or is something good because God commands it?" If goodness
