That one cannot have one's cake and eat it too is a popular, and correctly quoted English idiomatic proverb or figure of speech. The proverb means the same as "One can be in possession of one's cake, but is not allowed to eat it." This may also indicate having or wanting more than one can handle or deserve, or trying to have two incompatible things. The proverb's meaning is similar to the phrases, "you can't have it both ways" and "you can't have the best of both worlds." Conversely, in the positive sense, it would refer to "having it both ways" or "having the best of both worlds."
This concept, known as opportunity cost, is one of the most important economic concepts.
Although this saying is a commonly accepted idiom, it is flawed in its grammatical logic. The act of eating a cake must first involve possession of the cake, therefore the only way to eat a cake is to first have it. Regardless of this logical flaw, the phrase is still popular and is regarded as socially acceptable and understood.

Famous quotes containing the words cake and/or eat:
“Much of the ill-tempered railing against women that has characterized the popular writing of the last two years is a half-hearted attempt to find a way back to a more balanced relationship between our biological selves and the world we have built. So women are scolded both for being mothers and for not being mothers, for wanting to eat their cake and have it too, and for not wanting to eat their cake and have it too.”
—Margaret Mead (1901–1978)
“If one had to worry about one’s actions in respect of other people’s ideas, one might as well be buried alive in an antheap or married to an ambitious violinist. Whether that man is the prime minister, modifying his opinions to catch votes, or a bourgeois in terror lest some harmless act should be misunderstood and outrage some petty convention, that man is an inferior man and I do not want to have anything to do with him any more than I want to eat canned salmon.”
—Aleister Crowley (1875–1947)
