Idle is a term which generally refers to a lack of motion and/or energy.
Typically, when one describes a machine as idle, it is an objective statement regarding its current state. However, when used to describe a person, idle typically carries a negative connotation, with the assumption that the person is wasting their time by doing nothing of value. Such a view is reflected in the proverb "an idle mind is the devil´s workshop". This interpretation of idleness is not universal - it is more typically associated with Western cultures. Other cultures believe that simply being (doing nothing) has its own value, and they may also reject the West's definition of what is nothing and what is not.
The state of being idle is sometimes even celebrated with a few books on the subject of Idleness. How to Be Idle by Tom Hodgkinson is one such example from an author who is also known for his magazine - "The Idler", devoted to promoting its ethos of "idle living". Nobel Laureate Bertrand Russell's In Praise of Idleness; And other essays
is another book that explores the virtues of being idle in the modern society.

in the November 2004 Harper's Magazine, hinting at a post-scarcity economy, and linking conscious busy-ness with antidemocratic and fascist tendencies.
