In a time of fake news and alternative facts, being able to separate the proverbial scientific wheat from the pseudoscientific chaff is vitally important. But seeing the wide acceptance of a lot of dubious ideas, critical thinking does not come easily. So, how, then, do you tell science from bunk? Updating his 2010 book Nonsense on Stilts, evolutionary biologist and philosopher Massimo Pigliucci once again attacks this problem from many sides. Going far beyond cheap potshots at pseudoscience, I found a book that takes an equally serious look at the more insidious phenomena of think tanks and postmodernism, with a healthy side-serving of history of science. The result is a readable introspection on what science is and how it is done.
Spontaneous generation, the idea that life can arise out of non-living matter, is both alive and dead today. Current science accepts the idea that at some point in the distant past, complex self-replicating molecules arose, which formed the starting point of billions of years of unicellular life. But there is an obsolete side to this theory. For millennia, philosophers and scientists believed that all sorts of creatures could arise spontaneously from the mud and slime this book refers to. In the late 1850s, The French microbiologist Louis Pasteur performed experiments that definitively put the nail in the coffin for this idea.
Quite a few books have been written about the later discussions around this theory and its eventual demise (contemporary examples are John Farley’s The Spontaneous Generation Controversy from Descartes to Oparin or James Strick’s Sparks of Life: Darwinism and the Victorian Debates over Spontaneous Generation). Based on a three-part lecture series, this purposefully short book, which is not intended as a complete history, gives a whistle-stop tour of spontaneous generation from Antiquity to 1769. Are you ready?
