The turmeric patent and the grandmother's proof

From India·An enduring case

In 1995 a US patent was granted for using turmeric to heal wounds, a practice Indian households had relied on for generations. India's research council overturned it by producing ancient Sanskrit texts as prior art. Knowledge everyone had was only legally recognised once it appeared in writing that an office elsewhere would accept.

The concepts this raises

Each of these gives a class a different way into the same case.

EvidenceGrounds of Knowledge
What is offered in support of a claim. Evidence is not the same as proof: it raises or lowers how likely a claim is, and its force depends on how it was gathered, what it was gathered for, and what else it is consistent with. Asking what would count as evidence against a claim is usually more revealing than listing evidence for it.
PowerKnowledge and Society
The capacity to shape what counts as knowledge, who is heard, and what gets funded, published or taught. Power is not only censorship; setting an agenda, controlling a platform or being granted authority all change the knowledge that a community ends up with.

Where it sits in the knowledge framework

Methods and tools
The practices, conventions, instruments and forms of reasoning through which knowledge here is actually made, together with the assumptions those methods build in and what they are structurally unable to detect.
Ethics
The ethical questions internal to the knowledge itself: what may be investigated and how, what obligations the knowledge places on those who hold it, and the ethical constraints the discipline imposes on its own practitioners.

Areas of knowledge

Themes

The same ideas, somewhere else

Cases that raise a concept this one raises, but in a different area of knowledge or a different part of the world. That contrast is the point: it is what shows a student the concept travels.
