radical individualism

Radical individualism is the belief that personal autonomy and self-interest should take precedence over collective concerns or social obligations.

The term usually carries critical connotations, suggesting an excessive focus on the self at the expense of community, shared responsibility, or the common good: Critics blamed radical individualism for the erosion of civic life.

The phrase appears in political and philosophical discourse to characterize—often negatively—libertarian positions or modern Western culture generally.
