by Carl Pierer “(…) [M]y own body is the primordial habit, the one that conditions all others and by which they can be understood. Its near presence and its invariable perspective are not a factual necessity, since factual necessity presupposes them. (…) I observe external objects with my body, I handle them, inspect them, and…
by Carl Pierer *** M.C. Escher: Three Spheres II. * If we take an infinite collection of sets, all of which contain at least one element, is there a way to choose exactly one element from each of them? This seems to be just obviously true. After all, there is something in every set, so…
by Carl Pierer Fig. 1 Part II of Wittgenstein's Philosophical Investigations, also known as Philosophy of Psychology – A Fragment, contains a lengthy treatment of perception. He begins by drawing a distinction: Two uses of the word “see”. The one: “What do you see there?” – “I see this” (and then a description, a drawing,…
by Carl Pierer Published in 1932, Sunset Song is famed as one of the most important Scottish novels of the 20th century. As the first part in Lewis Grassic Gibbon's Trilogy A Scots Quair, it tells the story of Chris Guthrie coming of age in a rural community in Aberdeenshire. Set at the turn of…
by Carl Pierer Among the many tools available to mathematicians attempting to prove a statement is something called “proof by contradiction” or reduction ad absurdum. The general method of the proof is a very smug one: Let the statement to be proved be Φ. The strategy, then, is to suppose that Φ is false and…

by Carl Pierer A young man with a strong urge and deep conviction that he is destined to be of importance keeps a diary, which he calls “Diary of a Philosopher”. In fact, it is less of a diary than a notebook. He mentions and discusses ideas, arguments and impressions he had, articles he came…
by Carl Pierer Fig. 1: a Ceilidh as Braid This column last month, here, provided a first glimpse at the fascinating field of braids. Beneath their obvious beauty – to which their widespread aesthetic use bears testimony – lies a deep complexity. They allow for explorations of many beautiful areas of mathematics. They branch into…
by Carl Pierer Fig. 1 Braids are fairly simple to picture. A few interleaved strands of string, say, gives a complex and mesmerising object. They are aesthetically appealing, as their widespread use as ornament testifies. While most will be familiar with the standard braid used for braiding hair, there is basically no limit to complexity…
by Carl Pierer Let us suppose Pegasus does not exist. This simple idea has proven to lead to plenty of philosophical trouble. Because what exactly is the thing that does not exist? Quine puts the “Riddle of Non-being” as: “Nonbeing must in some sense be, otherwise what is it that there is not?” The problematic…
by Carl Pierer A question related to Zeno's famous paradoxes is the following: “Is it possible to complete an infinite sequence of tasks in a finite amount of times?” There seems to be something odd about supposing that an infinite amount of tasks, per definition without last task, should have been completed. In a beautiful…
by Carl Pierer Introduction The standard case of epistemic peer disagreement has two people going regularly to a café, where they regularly drink and eat. Sometimes A has to pay more, sometimes B. Often, they disagree about who has to pay how much – sometimes A gets it right, sometimes B. This time, A calculates…
by Carl Pierer Madam, Thank you for opening my eyes concerning the question whether students should be beaten to study Maths up to the age of 18. Your well-argued and logically impeccable column in the Times establishes beyond reasonable doubt that no one needs to know any Maths further and above the mere basics. It…
by Carl Pierer After having presented Clark and Chalmers' extended cognition hypothesis as well as two lines of argument against the hypothesis, the last article at this place ended with an intuitive, bad gut-feeling and a promise to develop this feeling into a full blown argument. Before making good on that promise, this article will…
by Carl Pierer Andy Clark and David Chalmers present a thesis of extended cognition and extended mind in their seminal 1998 paper: “The extended mind”. In it, they attack the idea that cognition and mind should be confined to the boundaries of our skull. Instead, they suggest, that the tools and instruments used in cognitive…
by Carl Pierer It is necessary that two men have the same number of hair, gold, and others.[i] This meme is taken from a scene in the Cohen brother's 1998 comedy “The Big Lebowski”. During a game of bowling, Walter, in the picture, gets annoyed at the other characters constantly overstepping the line. Drawing a…
by Carl Pierer Hard-working, dedicated snow plough driver, Nils Dickman (Stellan Skarsgård), is living a peaceful life with his wife Gudrun in a small, rural town in Norway. Just after being named Citizen of the Year, their son is found dead, apparently due to an overdose. The beautiful shots of wintery Norwegian landscapes, Nils' doubts…
by Carl Pierer In his Groundwork of the Metaphysics of Morals Kant states that an action has moral worth if and only if it is done from duty.Kant argues for his position by showing that morally right actions done from motives other than duty lack moral worth. He gives two examples: The Shopkeeper always gives…
by Carl Pierer A key ingredient to the good life seems to be that we, for ourselves, choose our goals and commitments. Indeed, Immanuel Kant goes as far as to claim that this is a necessary prerequisite for actions to have any moral worth at all. Individual Autonomy is widely accepted as an ideal. Kantianism…
by Carl Pierer It is a good situation for European students in Scotland. We get to study at excellent universities with outstanding research. We do not pay any tuition fees. The institutions are well funded. As part of the EU, access and living is easy. What more could we wish for? The campaign against Independence…
