The term insanity refers to madness, craziness or foolhardiness. Insane people are those who talk senseless things and make up all weird things in their mind. Some people also view insanity as madness to the extent that it leads to violation of social norms. Insanity is a term that is akin to mental stability or mental deficiency. Someone who is mentally deficient is said to be an insane person. In the words of H.P. Lovecraft, “Bunch together a group of people deliberately chosen for strong religious feelings, and you have a practical guarantee of dark morbidities expressed in crime, perversion, and insanity.”
Insane people believe in doing a particular task the same way repeatedly and expect the same set of results. Insanity is also deemed as positive by some people. Jean Dubuffet had once remarked,” For me, insanity is super sanity. The normal is psychotic. Normal means lack of imagination, lack of creativity.” She considered insanity as something particularly good.
