Joy is the state of being that allows one to experience feelings of intense, long-lasting happiness and contentment of life. It is closely related to, and often evoked by, well-being, success, or good fortune. Happiness, pleasure, and gratitude are closely related to joy but are not identical to it.
Distinction vs similar emotions
saw a clear distinction between joy, pleasure, and happiness: "I sometimes wonder whether all pleasures are not substitutes for Joy", and "I call it Joy, which is here a technical term and must be sharply distinguished both from Happiness and Pleasure. Joy has indeed one characteristic, and one only, in common with them; the fact that anyone who has experienced it will want it again... I doubt whether anyone who has tasted it would ever, if both were in his power, exchange it for all the pleasures in the world. But then Joy is never in our power and Pleasure often is."Michela Summa says that the distinction between joy and happiness is that joy "accompanies the process through and through, whereas happiness seems to be more strictly tied to the moment of achievement of the process... joy is not only a direct emotional response to an event that is embedded in our life-concerns but is also tightly bound to the present moment, whereas happiness presupposes an evaluative stance concerning one period of one's life or one's own life as a whole."
Affect theory
Joy is one of the less-studied emotions in the wider field of affect theory. Theorist Susanna Paasonen discusses this in her work "Ambiguous Affect", and presents the theory that excitement and joy are what shape a personality, building in past joys. She posits that joy and excitement build connections to things that grow into a larger web of interests, and studies this in relation to social media and how the fleeting and occasionally random nature of this excitement is difficult for companies to quantify in ways that are algorithmic, especially for social media.Another theorist that discusses joy is Sara Ahmed, a British Australian scholar who focus on affect theory, feminist theory, queer theory, critical race theory, and postcolonialism. In her article, "Happy Objects", she explores how objects can spark joy and happiness. Ahmed coined the term stickiness, stating emotions like happiness and joy being emotions that are doing. Ahmed states, "Happiness thus puts us into intimate contact with things. We can be happily affected in the present of an encounter; you are affected positively by something, even if that something does not present itself as an object of consciousness."
