"For [Rand] further holds that objective reality is readily accessible by solitary individuals using words and logic alone. This proposition - rejected by nearly all modern scientists - is essentially a restatement of the Platonic worldview, a fundamental axiom of which is that the universe is made up of ideal essences or 'values' (the term Rand preferred) that can be discovered, dispassionately examined, and objectively analyzed by those few bold minds who are able to finally free themselves from hoary assumptions of the past. Once freed, any truly rational individual must, by simply applying verbal reasoning, independently reach the same set of fundamental conclusions about life, justice and the universe. (Naturally, any mind that fails to do so must, by definition, not yet be free.)"
