“id” mixed media on wood 24x24"

Id is a term created by freud which is basically one third of our psychic apparatus, it controls our instinctual side. This is the definition according to wikipedia:

The id “knows no judgements of value: no good and evil, no morality….  It is regarded as "the great reservoir of libido”, the instinctive drive to create — the life instincts that are crucial to pleasurable survival. Alongside the life instincts came the death instincts… Freud considered that “the id, the whole person … originally includes all the instinctual impulses … the destructive instinct as well.”

“Symbiosis” ink and graphite on paper

Symbiosis (from Ancient Greek σύν “together” and βίωσις “living”)[1] is close and often long-term interaction between two or more different biological species. In 1877, Bennett used the word symbiosis to describe the mutualistic relationship in lichens.[2] In 1879, the German mycologist Heinrich Anton de Bary defined it as “the living together of unlike organisms.”
