If you ask a scientist a question about the philosophy of science, there’s a good chance the answer will feature just one or two philosophers. The name of the Austrian-born British philosopher Karl Popper (1902-94) will likely arise in the context of his principle of falsifiability, the ‘demarcation criterion’ that many scientists still use to distinguish science from non-science.
Early in 2004, a buoy was released into the waters off Argentina. Half of the buoy was dark and the other light, like a planet in relief. The buoy sailed east, accompanied by the vastness of the ocean and all the life it contains, the long-lived great humpback whales with their complex songs that carry for kilometers, and the short-lived Argentine shortfin squid. Along the way, many thousands of minuscule creatures were colonizing this new surface, which had appeared like a life raft in the open waters of the South Atlantic.
