The Turning Point of Life

Damien Hirst
Mother and Child, Devided, 1993

Damien Hirst

The impulses driving Damien Hirst’s work stem from dilemmas inherent in human life: ‘I am aware of mental contradictions in everything, like: I am going to die and I want to live for ever. I can’t escape the fact and I can’t let go of the desire’. The materials he uses often shock, but he says he ‘uses shock almost as a formal element . not so much to thrust his work in the public eye . but rather to make aspects of life and death visible’.

Fritjof Capra
The Systems View of Life, 1982
Chapter 8 of the “Turning Point”

As the notion of an independent physical entity has become problematic in subatomic physics, so has the notion of an independent organism in biology. Living organisms, being open systems, keep themselves alive and functioning through intense transactions with their environment, which itself consists partially of organisms. Thus the whole biosphere – our planetary ecosystem – is a dynamic and highly integrated web of living and nonliving forms. Although this web is multilevel, transactions and interdependencies exist among all its levels.

Most organisms are not only embedded in ecosystems but are complex ecosystems themselves, containing a host of smaller organisms that have considerable autonomy and yet integrate themselves harmoniously into the functioning of the whole. The smallest of these living components show an astonishing uniformity, resembling one another quite closely throughout the living world, as vividly described by Lewis Thomas.

Damien Hirst I Want You Because I Can’t Have You, 1992

There they are, moving about in my cytoplasm…..They are much less closely related to me than to each other and to the free-living bacteria out under the hill. They feel like strangers, but the thought comes that the same creatures, precisely the same, are out there in the cells of seagulls, and whales, and dune grass, and seaweed, and hermit crabs, and further inland in the leaves of the beech in my backyard, and in the family of skunks beneath the back fence, and even in that fly on the window. Through them, I am connected: I have close relatives, once removed, all over the place.

Although all living organisms exhibit conspicuous individuality and are relatively autonomous in their functioning, the boundaries between organism and environment are often difficult to ascertain. Some organisms can be considered alive only when they are in a certain environment; others belong to larger systems that behave more like an autonomous organism than its individual members; still other collaborate to build large structures which become ecosystems supporting hundreds of species.

Ichthyosaurus

Mark Dion
Ichthyosaurus, 2003

(pronounced IK-thee-oh-SAWR-us) Ichthyosaurus was an ichthyosaur, a marine reptile; it was not a dinosaur. This sleek animal could perhaps swim at speeds up to 25 mph (40 kph). Ichthyosaurus lived from the early Jurassic period until the early Cretaceous period, roughly 206 to 140 million years ago.
Anatomy: Ichthyosaurus was about 6.5 feet (2 m) long and ay have weighed about 200 pounds (90 kg). It had a tall dorsal fin, a half-moon-shaped tail, paddle-like flippers, and smooth skin. The nostrils were near the eyes on the top of the head. It had massive ear bones and large eyes, probably indicating that it had acute hearing and keen eyesight. These marine reptiles gave birth to live young.

Diet: Ichthyosaurus’ diet was mostly fish, but may have also included cephalopods (like straight-shelled belemnites).

Fossils: Hundreds of Ichthyosaurus fossils have been found in England, Germany, Greenland, and Alberta, Canada. Even fossilized dung (called coprolites) and fossilized skin impressions have been found. Ichthyosaurus, which means “fish lizard,” was named by Charles Koenig in 1818.
