 Freethinkers strive to build their opinions on the basis of facts, scientific inquiry, and logical principles, independent of any logical fallacies or intellectually limiting effects of authority, confirmation bias, cognitive bias, conventional wisdom, popular culture, prejudice, sectarianism, tradition, urban legend, and all other dogmas.Secular humanism focuses on the way human beings can lead happy and functional lives.It posits that human beings are capable of being ethical and moral without religion or God, it neither assumes humans to be inherently evil or innately good, nor presents humans as "above nature" or superior to it.
