"Individualism is the belief in the primary importance of the individual and in the virtues of self-reliance and personal independence. The foundation of individualism lies in one's moral right to pursue one's own happiness."
That is good.
"Collectivism is a belief in the primary importance of the group rather than the individual."
That is good too.
One problem is that collectives don't collectives don't invent anything and don't discover anything. Individuals do those things. Isaac Newton could not have been replaced by a million people.
