Descartes had it wrong. Not "I think, therefore, I am." But rather; "I think, therefore, I am."

I - The ego - Arises from thought. But thoughts themselves are mere strings of conciousness, abberant strands of synaptic impulses that somehow manage to coagulate into conclusions; into behavior. As Skinner said - Compared with the fascinating dramas played out in the depths of the mind, behaviour seems superficial! A single physical act requires dozens of independent thoughts, inextricably link but all very, very distinct.

Now, for an act such as murder - To willingly and deliberately take a sentient life - Imagine thr thought process that goes into that? Now, At this point, I must make clear the difference between the murder of a man in a pub brawl, and the careful strangulation of his wife while she showers. The former is an animal act - Brutish, with no regard for tact or circumstance. It is reflex, and it is base, therefore it is excluded from this argument.

No, the careful murder, of deliberate and particular effort - That is the most difficult of acts, mentally, emotionally and physically - And clearly, by extrapolation of Descartes, Jung, Skinner et al - It describes the most cunning man of all, the free killer, the one who despite his crimes walks untouched through society. Whether through manipulation of political sway or though pure forensic caution - The unimprisoned murderer, truly, is the cleverest by far.
