"Meaning is a much more fundamental notion than truth, indeed more fundamental even than the notion of "reality" itself. The basic argument was that claims about truth or reality are meanings made by people according to patterns that they have learned, and that trying to understand how and why people make the meanings they do is more useful than fighting over the truth of their claims."

“Scientific language that is correct and serious so far as teachers and students are concerned must follow these stylistic norms:”

“Multimodal presentations have an inherent critical potential to the extent that we learn how to use the images to deconstruct the viewpoint of the text, and the text to subvert the naturalness of the image.”

“The mystique of science is an essential tool for technocratic rule. Through it we are all taught that science, as the paradigm of all expert knowledge, has an objective, superior, and special truth that only the superintelligent few can understand. Science education, like it or not, does a great job in foisting these myths on most of us.”

“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.”

“We need a social theory that sees all social phenomena, including itself, as being partly the product of how people in a community deploy semiotic resources: how we mean, and what we mean, by every meaningful act.”

“We are constantly reading and listening to, writing and speaking, this text in the context of and against the background of other texts and other discourses.”
