 Emotions are on one hand constitutive of, embedded in, and on the other hand manipulated or instrumentalized by entities that are studied by sociology on a micro level, such as social roles and norms and 'feeling rules' the everyday social interactions and situations are shaped by, and, on a macro level, by social institutions, discourses, ideologies etc.For example, (post-)modern marriage is, on one hand, based on the emotion of love and on the other hand the very emotion is to be worked on and regulated by it.Likewise, modern science could not exist without the emotion of curiosity but it does narrow it leading sometimes to over-specialization of science.
