We can forget it for you wholesale

What would you forget?

Neurologists have found that memories stored on the same neuron can be selectively erased. 

In snails, anyway. You may be balking already. Keep in mind that such experiments are conducted on simpler lifeforms as a sort of "proof of concept" and come's not like there haven't be other eyebrow arching neurological studies. Yes of course the human brain is magnitudes of order more complex than a snail's. For perspective, let's go to Michio Kaku:

The human mind as the most sophisticated object in the known universe, more powerful than any of our current computers. Factually inarguable, despite all the stupid things we do.

Point being, would the erasure of selected memories even be possible with something so complex? Unknown, but the procedure in its most basic form does work. One of the more interesting findings of the study is that the erasure of selected memories does not affect the other memories stored on the same neurons.

Imagine it. Erase the bad and leave only the good.

Why not forget your phobias and irrational fears? Erase your fear of heights and rent that deluxe aerie downtown. Pass sites of traumatic experiences with no stress or fuss. Be haunted no more by your mistakes of past shame. Think of what this could do for those suffering from PTSD.

But what of the consequences?

Despite how sexy a new development of this kind may sound, prudence dictates that we examine the potential pitfalls. Science fiction certainly has. Upon reading the above linked article, I immediately thought of Philip K. Dick. His short story "Paycheck" is about an electrical engineer who is contractually obligated to have his memory erased after working on a secret project. "We Can Remember It For You Wholesale," the short story that became the film Total Recall (a favorite and probably Schwarzenegger's best) is about implanting memories, but not without its share of dire consequences nonetheless. Then again it begs the question: if you can erase, could you not implant?

That would likely be more difficult. As the study points out, the bad memories could be erased through a designer drug. For anything beyond erasure, it would likely require a direct brain-computer interface. Transhumanism once again.

Would you do it? Do you at last want to silence those ghosts and their screaming? Or do you need your pain? Does it guide you, inform your decisions, maybe even provide a sick sort of comfort?

I would argue that there are memories that deserve to be erased. I know exactly which ones I'd select.

Oh blissful amnesia...
