If we ignore the genetic possibilities that are beginning to present themselves, we are left with only two options in our quest to transplant man back into nature and become-animal.
The first is to experiment with the molecular bestiality outlined in the philosophy of Deleuze and Guattari which is conducted at the level of forces rather than form, but which is nevertheless a real procedure which has nothing to do with fantasy (even if it's very often tied to literature).
The second, is to continue at the molar level to investigate possibilities of animal transformation subscribed to by those for whom metamorphosis is crucial. For many pagans, for example, this idea is central within the magical world of shamanic religious practise; whilst for many fetishists, costumed pet-play is a popular niche activity within the erotic arena.
If, in the former realm the sexual element is sometimes played down in order that the spiritual aspect can be emphasized, nevertheless in both these worlds we find people who like to dress up and imitate animal behaviour, often in a heavily stylized and ritualistic manner.
Whatever we might think of this acting out, the key is it seems to enable participants to temporarily escape from the confines of their humanity - and, indeed, their underwear; metamorphosis seems to be a sweaty and somewhat uncomfortable process that invariably involves the violent discarding of clothes at some point.
To transform into an animal is thus not only liberating in that it allows one to live momentarily without bad conscience and to do things that are normally forbidden or frowned upon, but it promises also an altered state of being. Thus some therianthropes take animal transformation very seriously indeed, insisting that they genuinely possess the spirit or soul of an animal and that shape-shifting is far more than a type of role-play.
For me, I have to say, it all gets a bit much. And if, on the one hand, I admire the courage and mania of those who travel to the very limit of what it is to be human and defiantly declare themselves to be beasts, on the other hand I can do without the asceticism and judgemental snobbery of those therianthropes who regard other members of the furry community as frivolous sexual deviants lacking in respect for the animals they like to dress up as.
When push comes to shove, I'd sooner hang about with those individuals content to make animal noises in the bedroom, rather than those who howl at the moon. That is to say, I prefer those with zoosexual tastes rather than occult leanings; furverts rather than therianthropes.
