“Semiosis is, according to Peirce, "an action, or influence, which is, or involves, an operation of three subjects, such as a sign, its object, and its interpretant, this tri-relative influence not being in any way resolvable into an action between pairs".”

[O] : Introduction, O.I.
Semiotics and the Philosophy of Language (1984)
Context: The sign is usually considered as a correlation between a signifier and a signified (or between expression and content) and therefore as an action between pairs. Semiosis is, according to Peirce, "an action, or influence, which is, or involves, an operation of three subjects, such as a sign, its object, and its interpretant, this tri-relative influence not being in any way resolvable into an action between pairs".

General Quotes

“They are almost never required to make observations, formulate definitions, or perform any intellectual operations that go beyond repeating what someone else says is true.”

Neil Postman (1931–2003) American writer and academic

Teaching as a Subversive Activity (1969)
Context: In order to understand what kind of behaviors classrooms promote, one must become accustomed to observing what, in fact, students actually do in them. What students do in a classroom is what they learn (as Dewey would say), and what they learn to do is the classroom's message (as McLuhan would say). Now, what is it that students do in the classroom? Well, mostly they sit and listen to the teacher. Mostly, they are required to believe in authorities, or at least pretend to such belief when they take tests. Mostly they are required to remember. They are almost never required to make observations, formulate definitions, or perform any intellectual operations that go beyond repeating what someone else says is true. They are rarely encouraged to ask substantive questions, although they are permitted to ask about administrative and technical details. (How long should the paper be? Does spelling count? When is the assignment due?) It is practically unheard of for students to play any role in determining what problems are worth studying or what procedures of inquiry ought to be used. Examine the types of questions teachers ask in classrooms, and you will find that most of them are what might technically be called "convergent questions," but what might more simply be called "Guess what I am thinking " questions.
