When one looks at the alternative to individual expression, it’s herd mentality, do nothing original, raise no objection to the status quo, to follow others blindly. Not the most attractive of ideas, nor realistic. It works as a successful meme for some if not most animals, but humans have evolved to question, to analyse, to adapt based on ideas, which are all examples of individuality. So, essentially human, and not much we can do about it unless you can drug a population to act as a herd of animals.
Under that assumption, the negative effects of individualism can’t be completely eradicated, but they can be mitigated. As Huxley points out, pride, hatred and anger, are individual expressions that deny others freedom, whereas greed and lust necessarily don’t.
With this in mind, one can reject the former set entirely from one’s self without the need for constant proof. With greed and lust however, it will take analysis and judgement at every instance on the part of the individual to determine whether they are denying another of any freedom.
Admirable, but is it realistic?
