Human Nature: Addicted to Pushing Limits?

The two posters that I chose to discuss include the Hadron Collider poster and the Addiction poster. I would like to bring in our commonly used "Human Nature" that we tend to run into and have conflict with during class. I am not going to argue what constitutes Human Nature, instead I'd like to bring up the possibility that we (as part of our nature) are drawn/addicted to pushing the limits. The Hadron Collider illustrates this 'addiction' well.

We have established that we are all Cartesian, and that we believe everything can be figured out if we just put enough effort into what we want to accomplish. However, is part of being Cartesian also wanting to push the limits as far as they can go? Do we believe in limits? And does pushing these limits provide us with some sort of 'high' resulting in our addiction to pushing them further? I can see that we do have this constant urge to find out more, and in a way can see how we are addicted to finding out how far we can go. This can be linked to other events/things other than the Hadron Collider, (space exploration, designer babies, vaccinations, etc.)

Again, I am not trying to define what human nature is. I just think it's interesting that we continue to act in similar patterns, and to say it is an addiction may also be 'pushing it'.
