  Alfred Tarski - Wikipedia, the free encyclopedia
Alfred Tarski (January 14, 1901, Warsaw Poland – October 26, 1983, Berkeley California) was a Polish-born logician and mathematician of considerable philosophical importance.
Tarski and his Berkeley colleagues and students discovered cylindric algebras, which are to first-order logic what the two-element Boolean algebra is to classical sentential logic.
Tarski's semantic methods, whose culmination was the model theory he and a number of his Berkeley students developed in the 1950s and 60s, radically transformed Hilbert's proof-theoretic metamathematics.

Alfred Tarski, original name Alfred Teitelbaum (January 14, 1901 - October 26, 1983) was a Polish logician considered to be one of the greatest logicians of all time in a manner after Aristotle, Gottlob Frege, and Kurt Gödel.
The question of whether Tarski's notion was the modern one turns on the question of whether he intended to admit models with varying domains (and in particular, models with domains of different cardinalities).
Tarski ends his paper by pointing out that his definition of logical consequence depends upon a division of terms into the logical and the extra-logical and he expresses some skepticism that any such objective division will be forthcoming.

Tarski taught logic at the Polish Pedagogical Institute in Warsaw from 1922 to 1925 then in that year he was appointed Docent in mathematics and logic at the University of Warsaw.
Tarski was successful in obtaining permission to remain in the United States, and he then tried, with the help of many European friends, to arrange for his family to escape and join him in the United States.

 Tarski's Truth Definitions   (Site not responding. Last check: 2007-11-04)
Tarski assumed, in the manner of his time, that the object language L and the metalanguage M would be languages of some kind of higher order logic.
One sometimes says that Tarski's definition of satisfaction is compositional, meaning that the class of assignments which satisfy a compound formula F is determined solely by (1) the syntactic rule used to construct F from its immediate constituents and (2) the classes of assignments that satisfy these immediate constituents.
So for this section of the paper, Tarski allows one and the same sentence to be given different interpretations; this is the exception to the general claim that his object language sentences are fully interpreted.

O just added some bio details and a reference to Tarski 2002.
There's a new biography of Tarski out and it looks pretty interesting.
For example, we all have our favorite writers, and Tarski is certainly one of mine, but an encyclopedia begins to sound rather silly when a large %-age of its biographical articles start out saying "X is considered the greatest Y of era Z".

 Alfred Tarski - Cambridge University Press
Alfred Tarski, one of the greatest logicians of all time, is widely thought of as ‘the man who defined truth’.
Tarski was a charismatic teacher and zealous promoter of his view of logic as the foundation of all rational thought, a bon-vivant and a womanizer, who played the ‘great man’ to the hilt.
She is a well-known biographer, and he was a student of Tarski and is a distinguished logician in his own right, as well as the editor of Kurt Gödel's papers.

 Semantical Paradoxes in Languages
Tarski questions whether we can specify the assertible sentences in a colloquial language (he actually uses the term natural language in this later work) to the extent that it is possible to meaningfully assert such a language is inconsistent.
As Tarski puts it, we have a structural description of the primitive symbols the language and the rules for constructing expressions, and a structural description of the basic axioms and rules of inference for the assertions of the language.
Tarski's response to this possibility is to note that it would be superfluous to stress the consequences of changing the logic ([Tarski44,§8]).

 Logical Consequence, Philosophical Considerations [Internet Encyclopedia of Philosophy]
Tarski says that by virtue of being formal, knowledge that X follows logically from K cannot be affected by knowledge of the objects that X and the sentences of K are about.
Tarski thinks that an adequate response must reflect the common concept of logical consequence, i.e., the concept as it is ordinarily employed.
Tarski says that future research will either justify the traditional boundary between the logical and the non-logical or conclude that there is no such boundary and the concept of logical consequence is a relative concept whose extension is always relative to some selection of terms as logical (p.

 Alfred Tarski Biography / Biography of Alfred Tarski World of Mathematics Biography
Alfred Tarski made considerable contributions to several areas of mathematics, including set theory and algebra, and his work as a logician led to important breakthroughs in semantics--the study of symbols and meaning in written and verbal communication.
Tarski's research also proved useful in the development of computer science, and he became an influential mentor to later mathematicians as a professor at the University of California at Berkeley.
Born Alfred Tajtelbaum in Warsaw, Poland (then part of Russian Poland), on January 14, 1901, Tarski was the elder of two sons born to Ignacy Tajtelbaum, a shopkeeper of modest means, and Rose (Iuussak) Tajtelbaum, who was known to have an exceptional memory.

As for a usable or workable definition of truth (for colloquial language), I think that the texts which Alfred Tarski has formulated in the first paragraph of his well-known article (sub (1) to (6) - bibliographical notice, see below), and which he thoroughly criticises, disapproves and radically rejects, aren't that bad at all.

I nevertheless, at the same time, strongly wish to express my great admiration and my sincere appreciation for the laborious efforts Alfred Tarski achieved in his arduous search for an explanation for the liar phenomenon and for a truth-definition that could give him satisfaction.

Tarski is as famous for his contributions to philosophy as for his contributions to mathematics.
Tarski's definitions of truth and of consequence employ the tools of modern mathematical logic in order to characterize classically accepted concepts.
As Tarski emphasizes in his 1969 "Scientific American" article "Truth and Proof", just as truth, which is ontic and objective, is a precondition for proof (or demonstrative knowledge), which is epistemic and to an extent subjective, consequence is an ontic and objective precondition for inference, which like proof is epistemic and inescapably subjective.
