The concept of tradition, as the notion of holding on to a previous time, is also found in political and philosophical discourse. For example, it is the basis of the political concept of traditionalism, and also strands of many world religions including traditional Catholicism. In artistic contexts, tradition is used to decide the correct display of an art form. For example, in the performance of traditional genres (such as traditional dance), adherence to guidelines dictating how an art form should be composed are given greater importance than the performer's own preferences. A number of factors can exacerbate the loss of tradition, including industrialization, globalization, and the assimilation or marginalization of specific cultural groups. In response to this, tradition-preservation attempts have now been started in many countries around the world, focusing on aspects such as traditional languages. Tradition is usually contrasted with the goal of modernity and should be differentiated from customs, conventions, laws, norms, routines, rules and similar concepts.
