Happiness, pleasure or joy is the emotional state of being happy. The definition of happiness is one of the greatest philosophical quandaries. Proposed definitions include freedom from want and distress, consciousness of the good order of things, assurance of one's place in the universe or society, inner peace, and so forth. More generally, though, it can be defined as the state which humans and other animals are behaviorally driven towards, to counter external forces which would otherwise lead to unhappiness (and presumably eventual death). Associated emotions include joy, exultation, delight, bliss, and love. Antonyms include suffering, sadness, grief, and pain. The term pleasure (like its opposite pain) is often used to specifically indicate localized, physical sensations, while happiness is sometimes used to refer specifically to a long-term, inner feeling.
