In philosophy, nihilism (; from Latin nihil 'nothing') is any viewpoint, or a family of views, that rejects generally accepted or fundamental aspects of human existence, namely knowledge, morality, or meaning. There have been different nihilist positions, including that human values are baseless, that life is meaningless, that knowledge is impossible, or that some other highly regarded concepts are in fact meaningless or pointless. The term was popularized by Ivan Turgenev and more specifically by his character Bazarov in the novel Fathers and Sons. .
