"Social change cannot come above the intellect, it comes about by people suffering. And the more people are related to that, the more they lose respect for an existing government. They will seek another direction. If there are too many people who seek a new direction, then the existing government calls upon the army and police to manage society – that is called fascism."

My major preoccupation is the question, 'What is reality ?' Many of my stories and novels deal with psychotic states or drug-induced states by which I can present the concept of a multiverse rather than a universe. Music and sociology are themes in my novels, also radical political trends; in particular I've written about fascism and my fear of it.
