Our species, Homo sapiens, rose in Africa some 300,000 years ago. The objects that early humans made and used, known as the Middle Stone Age material culture, are found throughout much of Africa and include a vast range of innovations. Among them are bow and arrow technology, specialised tool forms, the long-distance transport of objects […]
If you ask people to list the most intelligent animals, they’ll name a few usual suspects. Chimpanzees, dolphins and elephants are often mentioned, as are crows, dogs and occasionally pigs. Horses don’t usually get a look in. So it might come as a surprise that horses possess an unusual skill, widely considered an indicator of […]
One fascinating, as well as disconcerting fact about the evolution of Greek thought about science is that, almost immediately after the end of the ‘Classical’ period of philosophy, and particularly after Aristotle’s founding work on both philosophy and science, these two activities seemed to follow two radically separate courses. Actually, Greek science achieved its peak […]
Let me make a short interruption in our series about the prehistory of philosophy of science, to discuss a completely different point. I am writing this now, just because in the last days I think I have been able to clearly formulate a specific perplexity that for many years I had felt about what we […]
According to Geoffrey of Monmouth, whose History of the Kings of Britain was written in 1136, the mysterious monoliths at Stonehenge were first spirited there by the wizard Merlin, whose army stole them from a mythical Irish stone circle called the Giants’ Dance. Centuries before the development of rudimentary geology, Geoffrey’s exotic theory – that […]
Around 5,000 years ago (c. 3100 BC), what we know today as Ancient Egypt came into existence. A thousand years either side, and other such “primary states” had also arisen across the world, in Mesopotamia, North China, the Indus Valley and other locations. But why did human social dynamics change so dramatically in such a […]
Besides being one of the main pioneers of scientific thought, Aristotle is the author of the work that can unquestionably be considered the first book explicitly and exclusively devoted to what we can call ‘philosophy of science’ . This small book is known by the rather insipid name of Posterior Analytics ( Ἀναλυτικὰ ὑστέρων ) […]
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 […]
