LaVeyan Satanism has been characterised as belonging to the political right rather than to the political left. The historian of Satanism Ruben van Luijk characterised it as a form of "anarchism of the Right". LaVey was anti-egalitarian and elitist, believing in the fundamental inequality of different human beings. His philosophy was Social Darwinist in basis, having been influenced by the writings of Herbert Spencer, Friedrich Nietzsche, and Ayn Rand. LaVey stated that his Satanism was "just Ayn Rand's philosophy with ceremony and ritual added". Characterising LaVey as a Nietzschean, the religious studies scholar Asbjørn Dyrendal nevertheless thought that LaVey's "personal synthesis seems decidedly his own creation, even though the different ingredients going into it are at times very visible." Social Darwinism is particularly noticeable in "The Book of Satan", where LaVey uses portions of Redbeard's "Might Is Right", though it also appears throughout in references to man's inherent strength and instinct for self-preservation.
