Less is more: Signatures, cities and hash codes
In 1997, the Hubble Space Telescope’s Imaging Spectrograph (STIS) picked up the signature of a black hole. Instead of a vertical straight scan line, the STIS showed an S shape. Signatures point to the presence of something (a referent). But you see the thing only indirectly, i.e. you get to know that the referent exists, … Continue reading
Beware of this message
Generals and soldiers must pass messages up and down the chain of command in secret to avoid interception by the enemy. The same applies to cities. Writing in the 1600s, the English natural philosopher (and proto-semiotician) John Wilkins (1614-1672) affirmed that “there are certain ways to discourse with a friend, though he were in a … Continue reading
COVID couture
Why cover your nose and mouth with fabric during an epidemic? Apart from any practical advantages, and disadvantages, a face mask is a sign. Whether or not they are effective in blocking viruses, (non-surgical) face masks transmit messages. Before the current crisis I wrote a book on the founder of semiotics Charles Sanders Peirce (1839-1914). … Continue reading
Recursion again
In mathematics and computer programming, a recursive definition is one that defines a process in terms of itself: a branch of a tree is a branch that ends in smaller branches. That’s recursive as the definition of a branch in this case refers to a definition of a branch. A program that draws a branching … Continue reading
Architecture’s pragmatic turn
There was once a linguistic turn. The philosopher Richard Bernstein describes the ascent after WWII of analytical philosophy with its focus on plain language and clear argumentation, as it pushed aside other philosophy deemed imprecise and speculative. But now we have entered the pragmatic turn. Bernstein published a book in 2010 entitled just that: The … Continue reading
The immoveable typist
Johannes Gutenberg’s (1400-1468) printing press allowed knowledge to accumulate — and contributed to the idea that knowledge accumulates. But there were other benefits as it released energies from the laborious task of copying and transcribing texts by hand and other cumbersome and unreliable processes for reproduction, such as woodblock printing. According to social geographer and … Continue reading
This man has a sign
The semiotic philosopher Charles Sanders Peirce said enigmatically that “man is a sign” (54). I’ve referred to this in a previous post. This statement hints at something significant about the use of language. We humans are capable of profound transformation under the operations of the sign. But I find it easier to think in terms … Continue reading
Hustle, twitter, bells and banter
Free beer! C.S. Peirce and semioticians make much of the meaningful call out of someone like a street vendor. A cry or call out from someone giving away, selling or hustling goods at a market fits one of Peirce’s sign categories. To be precise, it is a kind of dicent indexical legisign. The sign is complete … Continue reading
Rhematic architecture
For the non-linguist, the rheme is one of the most difficult concepts in semiotics. It is not in architecture’s lexicon, and it’s hard to think of its relevance outside of language study. In fact, in material culture (e.g. architecture) we are more comfortable with the structure of metaphor than with the theme-rheme structure, as I … Continue reading
Full indexical jacket
Art in the 1970s shifted to the indexical, according to Rosalind Krauss, and away from the symbolic. “As distinct from symbols, indexes establish their meaning along the axis of a physical relationship to their referents. They are the marks or traces of a particular cause, and that cause is the thing to which they refer, … Continue reading
