Criticism
It has been argued that, because we cannot understand advanced civilizations, we cannot predict their behavior; thus, Kardashev's visualization may not reflect what will actually occur for an advanced civilization. This central argument is found in the book Evolving the Alien: The Science of Extraterrestrial Life.
Robert Zubrin uses the terms to refer to how widespread a civilization is in space, rather than to its energy use. In other words, a Type I civilization has spread across its planet, a Type II has extensive colonies in its respective stellar system, and a Type III has colonized its galaxy.

Famous quotes containing the word criticism:
“The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”
—Camille Paglia (b. 1947)
“As far as criticism is concerned, we don’t resent that unless it is absolutely biased, as it is in most cases.”
—John Vorster (1915–1983)
“People try so hard to believe in leaders now, pitifully hard. But we no sooner get a popular reformer or politician or soldier or writer or philosopher—a Roosevelt, a Tolstoy, a Wood, a Shaw, a Nietzsche, than the cross-currents of criticism wash him away. My Lord, no man can stand prominence these days. It’s the surest path to obscurity. People get sick of hearing the same name over and over.”
—F. Scott Fitzgerald (1896–1940)
