The word error entails different meanings and usages relative to how it is conceptually applied. The concrete meaning of the Latin word "error" is "wandering" or "straying". Unlike an illusion, an error or a mistake can sometimes be dispelled through knowledge (knowing that one is looking at a mirage and not at real water does not make the mirage disappear). For example, a person who uses too much of an ingredient in a recipe and has a failed product can learn the right amount to use and avoid repeating the mistake. However, some errors can occur even when individuals have the required knowledge to perform a task correctly. Examples include forgetting to collect change after buying chocolate from a vending machine, forgetting the original document after making photocopies, and forgetting to turn the gas off after cooking a meal. Some errors occur when an individual is distracted by something else.

Famous quotes containing the word error:

    Knowledge is ancient error reflecting on its youth.
    Francis Picabia (1878–1953)

    There are strange flowers of reason to match each error of the senses.
    Louis Aragon (1897–1982)

    There is a lot of difference between tempting and leading into error. God tempts but does not lead into error. To tempt is to provide opportunities for us to do certain things if we do not love God, but putting us under no necessity to do so. To lead into error is to compel a man necessarily to conclude and follow a falsehood.
    Blaise Pascal (1623–1662)
