Hollywood blockbusters such as X-men, Gattaca and Jurassic World have explored the intriguing concept of “germline genome editing” – a biomolecular technique that can alter the DNA of sperm, eggs or embryos. If you remove a gene that causes a certain disease in an embryo, not only will the baby be free of the disease […]
During the time Aristotle spent far from Athens after the death of Plato, he lived for a few years on the island of Lesbos and in some Asia Minor cities that surrounded it, an area where a kind of ‘franchise’ of the Academy had been founded a few years ago under the patronage of the […]
Isabel Hofmeyr, University of the Witwatersrand and Charne Lavery, University of Pretoria On many beaches around the Indian Ocean, keen observers may spot bits of broken pottery. Washed smooth by the ocean, these shards are in all likelihood hundreds of years old, from centres of ceramic production like the Middle Eastern Abbasid caliphate and the […]
An ancient legend from the Indonesian island of Flores speaks of a mysterious, wild grandmother of the forest who eats everything: the ‘ebu gogo’. According to folklore, such tiny, hairy people as her once roamed the tropical forests alongside modern humans, eating crops and sometimes even human flesh. For decades, ethnographers documented the tale, recording […]
If Plato’s reflections on the nature of epistéme was the starting point of what we can take as an authentic ‘philosophy of science’, and even if his views were probably the most influential during the rest of the Ancient times (as we shall confirm in subsequent entries), the truth is that science as we know […]
We shall conclude with this entry our discussion of Plato’s view of science, the main conclusions of the two former ones being, in the first place, the idea that ‘scientific knowledge’ ( epistēmē ) consists in the knowledge of eternal, intelligible Forms, whereas material things are imperfect copies of the former, and only graspable with […]
The third person effect phenomenon was described by Davidson in 1983 . People tend to think that media influence other people more than themselves. This self reinforcement is a key mechanism to understand the different effects caused by the media on their audience, since people are motivated to maintain a positive image of themselves by […]
Preamble In the period 2015-2019, I was hired as a mathematician by a biology department in order to perform a research that eventually would become my doctoral thesis. This text is adapted from the last chapter of that thesis, “Cycles and interactions: A mathematician among biologists” (full text available here ). The symbiosis between mathematics […]
In the past entry we introduced Plato’s model of the degrees of knowledge , ‘the simile of the line’, according to which the primordial difference between ‘science’ and ‘mere opinion’ is not so much about the ‘methods’ employed to reach one or the other (as will be assumed in modern times), but about the nature […]
When did something like us first appear on the planet? It turns out there’s remarkably little agreement on this question. Fossils and DNA suggest people looking like us, anatomically modern Homo sapiens, evolved around 300,000 years ago. Surprisingly, archaeology – tools, artefacts, cave art – suggest that complex technology and cultures, “behavioural modernity”, evolved more […]
