Healthcare systems across the globe are struggling with increasing costs and worsening outcomes. This presents those responsible for overseeing healthcare with a challenge. Increasingly, policymakers, politicians, clinical entrepreneurs and computer and data scientists argue that a key part of the solution will be ‘Artificial Intelligence’ (AI) – particularly Machine Learning (ML). This argument stems not from the belief that all healthcare needs will soon be taken care of by “robot doctors.” Instead, it is an argument that rests on the classic (...) counterfactual definition of AI as an umbrella term for a range of techniques that can be used to make machines complete tasks in a way that would be considered intelligent were they to be completed by a human. Automation of this nature could offer great opportunities for the improvement of healthcare services and ultimately patients’ health by significantly improving human clinical capabilities in diagnosis, drug discovery, epidemiology, personalised medicine, and operational efficiency. However, if these AI solutions are to be embedded in clinical practice, then at least three issues need to be considered: the technical possibilities and limitations; the ethical, regulatory and legal framework; and the governance framework. In this article, we report on the results of a systematic analysis designed to provide a clear overview of the second of these elements: the ethical, regulatory and legal framework. We find that ethical issues arise at six levels of abstraction (individual, interpersonal, group, institutional, sectoral, and societal) and can be categorised as epistemic, normative, or overarching. We conclude by stressing how important it is that the ethical challenges raised by implementing AI in healthcare settings are tackled proactively rather than reactively and map the key considerations for policymakers to each of the ethical concerns highlighted.

Notions such as śūnyatā, catuṣkoṭi, and Indra's net, which figure prominently in Buddhist philosophy, are difficult to readily accommodate within our ordinary thinking about everyday objects. Famous Buddhist scholar Nāgārjuna considered two levels of reality: one called conventional reality, and the other ultimate reality. Within this framework, śūnyatā refers to the claim that at the ultimate level objects are devoid of essence or "intrinsic properties", but are interdependent by virtue of their relations to other objects. Catuṣkoṭi refers to the (...) claim that four truth values, including contradiction, are admissible in reasoning. Indra's net refers to the claim that every part of a whole is reflective of the whole. Here we present category theoretic constructions that are reminiscent of these Buddhist concepts. The universal mapping property definition of mathematical objects, wherein objects of a universe of discourse are defined not in terms of their content, but in terms of their relations to all objects of the universe is reminiscent of śūnyatā. The objective logic of perception, with perception modeled as [a category of] two sequential processes (sensation followed by interpretation), and with its truth value object of four truth values, is reminiscent of the Buddhist logic of catuṣkoṭi. The category of categories, wherein every category has a subcategory of sets with zero structure within which every category can be modeled, is reminiscent of Indra's net. Our thorough elaboration of the parallels between Buddhist philosophy and category theory can facilitate better understanding of Buddhist philosophy, and bring out the broader philosophical import of category theory beyond mathematics.

Notions such as Sunyata, Catuskoti, and Indra's Net, which figure prominently in Buddhist philosophy, are difficult to readily accommodate within our ordinary thinking about everyday objects. Famous Buddhist scholar Nagarjuna considered two levels of reality: one called conventional reality and the other ultimate reality. Within this framework, Sunyata refers to the claim that at the ultimate level objects are devoid of essence or "intrinsic properties", but are interdependent by virtue of their relations to other objects. Catuskoti refers to the (...) claim that four truth values, along with contradiction, are admissible in reasoning. Indra's Net refers to the claim that every part of a whole is reflective of the whole. Here we present category theoretic constructions which are reminiscent of these Buddhist concepts. The universal mapping property definition of mathematical objects, wherein objects of a universe of discourse are defined not in terms of their content, but in terms of their relations to all objects of the universe is reminiscent of Sunyata.

Ramayan Through Kundalini Yoga Shodasi is an ideal read for Sanskrit-literate readers who are open to eclectic yogarthas and connotative meanings -------- So you thought Vyasa was before Valmiki, Mahabharat was before Ramayan, Rama a Vishnu avatar, and tantrism distinct from vedism? Think again. In Shodasi: Secrets of the Ramayana, Telugu poet Seshendra Sharma re-reads the Ramayan to come up with a number of new conclusions. Much of the book sets out to prove that Ramayan was written before the Mahabharat. (...) Sharma discusses how Indra is cited more often than Vishnu, thus placing the context of the Ramayan closer to Vedic than Puranic thought. He quotes from the Mahabharat to show how it follows descriptions of hills, rivers from the Ramayan. The Mahabharat has some prose, and therefore, it must have been composed after Ramayan, which is entirely in poetry. These are only some of the numerous reasons that Sharma offers to suggest a new sequence of our itihasas. Sharma’s book is also an experimental reading of the Ramayan through the interpretive lens of what he calls Kundalini yoga. Hanuman’s flight to Sri Lanka gets a new interpretation. “Charana Charite Pathi” is interpreted as the path of Kundalini, and the first verse of the Sundara Kanda “Tatho Ravana Nithayah” is interpreted by Sharma to refer to Hanuman traversing the sushumna nadi of the Kundalini. Trijata’s dream becomes the Gayatri mantra through an imaginative recasting of words as numbers. Gaja (elephant) means eight, danta (teeth) means thirty-two, and maha-gaja-chaturdantam somehow also adds up to 32 syllables, which is the number of syllables in the Gayatri mantra. That Trijata’s dream is halfway through the Ramayan also becomes significant for Sharma, he calls it the ‘central bead’ in the Ramayan garland of 24,000 beads. Identifying 32-syllables as the Gayatri follows a convention, for mantras are referenced by the number of syllables; however, it is the “secret” yogartha—or mystical, anagogical translations—derived by Sharma that becomes problematic, unless he is considered an authority in his own right. conclude that the name Sundarakand is unrelated to any descriptions of beauty of any of the main characters in the Ramayan. However, Soundarya and Tripura-Sundari are well-known conventions in the tantric tradition and hence, Sharma concludes that Sundarakand derives its name from Shakti’s beauty, and “Sundara-Hanuman” means “Hanuman who is a devotee of Devi” (117). A coda in this book is about the benedictory verse in Kalidasa’s Sakuntalam which has traditionally been understood to refer to Ishwara. Sharma re-interprets this verse highlighting the “eight forms” of the last line as the eight forms of Devi that please Ishwara. This book is suitable for a reader who is Sanskrit-literate and open to eclectic yogarthas and connotative meanings. Sharma cites substantially from the Ramayan in roman but without diacritics, this is difficult to follow; and he does not always include translation. Sharma often cites commentators without citing names and sources. It is not clear why the book is called Shodasi—readers may note, this book is not about the Srividya tradition. Even if the reader is unconvinced by Sharma’s reasoning or methodology, the free flow of references may prove absorbing for a reader interested in the subject. This could also be an eclectic reference for a scholar researching tantric elements in the Ramayan. - Mani Rao The Sunday Standard Magazine The New Indian Express 29th November 2015 . (shrink)
