Def1)A person who lives life dominated by their own personal values, beleifs, and ambitions. A true "individual" doesn't even realize they are an individual, they are just doing their thing and it feels natural to them. Anyone who calls themselves an individual and thinks they arn't part of culture and society is stupid and just as unindividual as they people they look down on for joining mainstream culture. Listening to obscure indie music doesn't make you an individual. Wearing trendy clothes does not make you an individual.
Def2)But really, everyone is an individual, the previously mentioned "true individual" who does their thing because it comes naturally to them is really just a confident, intelligent person who stands out from the crowd, but in actuallity is no different that everyone else just because humans, in a basic sense, live for the same things (their values, ambitions, personal relationships, dreams, ect). Its impossible not to be an individual, because people have evolved as societies for the last million years and your attitude can not change that. Everyone has their own values and beleifs, but their behaviour is shaped in varying degrees by their setting and role in a situation. This is undeniable and undebatable fact of human existance. The people who appear to be "individual" just have their behaviour and morals/ideas influenced by a different aspect of life than the observer's own beliefs.
Def1) Jane- "I love you so much, Bill, you're just such an individual"
Bill- "What? I'm not doing anything special, I'm just living life"
Ellen- "I'm an individual. I'm not controlled by the mindless drone that is mainstream culture. I don't get my ideas by watching MTV like everyone else. I listen to Arcade Fire. I have a red streak in my hair. Why are people such sheep?"
Drederick- "Bitch shut the fuck up, you and your friends all look the same and every high school has a group of you sorry losers. You arn't unique, and you arn't individual"
Def2) Everyone is an individual. But not everyone realizes that, so we get cultural bullshit from a few lame high school kids.
