Science has often presented itself, intentionally or unintentionally as a "truer" or even the true way of talking about the world. In science classro… - Jay Lemke

Each community, each discourse tradition, has its own canons of intertextuality, its own principles and customs regarding which texts are most relevant to the interpretation of any one text

In terms of language, we do know what a scientific theory or conceptual system must be: it is a thematic pattern of semantic relationships in a subject, one that is reconstructed again and again in nearly the same ways by members of a community.

The biological organism and the social persona are profoundly different social constructions. The different systems of social practices, including discourse practices, through which these two notions are constituted, have their meanings, and are made use of, are radically incommensurable. The biological notion of a human organism as an identifiable individual unit of analysis depends on the specific scientific practices we use to construct the identity, the boundedness, the integrity, and the continuity across interactions of this unit. The criteria we use to do so: DNA signatures, neural micro-anatomy, organism-environment boundaries, internal physiological interdependence of subsystems, external physical probes of identification at distinct moments of physical time -- all depend on social practices and discourses profoundly different from those in terms of which we define the social person.
