I've always been a big believer in the nihilism viewpoint even before I knew the term existed. Basically Nihilism is the philosophical viewpoint that denies or lacks belief in any or all of the reputedly meaningful aspects of life.
Each time I bring up this theory of there being no morality, the response I get is something in the line of "...deep down everyone is born with a good conscience and although some people lose/suppress their conscience and become evil". I rather disagree with this point of view. I think we can't really know for sure if a conscience exists and given how much I've seen how our environment changes our point of view of life, I'm leaning towards the direction that things like your conscience and morality are based on your environment.
Environment doesn't just mean geographical location when I speak about environment It involves everything which you're exposed to after you're born, ie the types of movies you watch, the things you learn at school, the friends you move around with, the parents/siblings you have and what they teach you and even you, the books you read, the weather you grew up in etc. I will never know for sure if the environment is the reason for 100% of our actions since there's no body who grew up in an un-influenced environment but from what I've observed. The environment has a lot of influence on everything we do/think and become. e.g If If I want to buy a shoe right now, I won't even look at the gucci because I can't afford it does me choosing a different shoe a free choice? Or was the choice influenced by how much money I have?
Another good argument I get when I share this philosophy with others is something like "... Arnold I understand what you say but surely you'll agree with me that raping a child is a bad thing ...". Well I'll argue that it's just a fact. It becomes a "bad" thing when we add context to it: context here means our "conscience" or our belief system of what we think should be promoted and what we think shouldn't. I guess the point is if we don't compare, we can't know if It's good or bad.
In any-case, I think for most people we have our personal sense of morality or line where we say, anything above that line is good and everything below that line is bad. I think that's a nice way to avoid thinking about this questions like this and be satisfied with your choices/decisions but I guess the only drawback of this personal bad/good is that it doesn't help people live better in a community. If for me personally, raping is bad and for you, raping people is a good thing, then it will be very difficult for us to live together since we won't have common interest. I guess that's why we have governments/education to help shape our morality so we can agree on some concepts that ensure that we can live better in a community.
While I believe that there's no "divine"/supernatural "conscience" i do think that as a society, we need some notion of morality or write/wrong in-order for us to live together as a society. I guess the only drawback of this is what's happening in the wold right now where we have different "micro" societies who have very conflicting views with others but I guess it's still better to have this conflicting viewpoints at a community level than to have it at a personal level.
