Concision (also called brevity, laconicism, or conciseness) is a writing principle of eliminating redundancy. For example, a sentence of "It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." may be expressed more concisely as "Most arguments must demonstrate their truth to readers." – the observations that the statement is a fact and that readers are its audience are redundant, and it is unnecessary to repeat the word "arguments" in the sentence.
A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all his sentences short, or that he avoid all detail and treat his subjects only in outline, but that every word tell.— Elementary Principles of Composition, The Elements of Style
Succinctness is a related concept. "Laconic" speech or writing refers to the pithy bluntness that the Laconian people of ancient Greece were reputedly known for. In computing, succinct data structures balance minimal storage use against efficiency of access. In algorithmic game theory, a succinct game is one that may be accurately described in a simpler form than its normal representation.

Archived 2012-06-14 at the Wayback Machine ""It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." Notice the beginning of the sentence: "it is a fact that" doesn't say much; if something is a fact, just present it. So begin the sentence with "most arguments..." and turn to the next bit of overlap. Look at "readers, that is the audience"; the redundancy can be reduced to "readers" or "audience." Now we have "Most arguments must try to convince readers that the arguments are true." Let's get rid of one of the "arguments" to produce "Most arguments must demonstrate (their) truth to readers," or a similarly straightforward expression."
