The reductionist assumptions are not changed by mere negations. We need different conceptual models to think and study differently. Rather than disparaging formal systems, we can grasp the whole cycle. Systems emerge from, are used in, and flow back into the wider context in which people work. A new kind of scientific term has been devised, that incorporates both scientific and life world versions.
Postmodernism is wrong to oppose conceptual models.
We get trapped in the scientistic objectivist model because it is so largely the only one. A new kind of truth and objectivity. There is no top-down determination by culture, history, or language. The infant comes with the capacity for all existing cultures, and more. Each culture develops dimensions that other cultures leave unexplored.
