Psychiatric term not widely used. Scholars of psychism prefer to talk about personality or anancastic disorder, obsessive compulsive personality disorder (TPOC) characterized by an obsessive preoccupation with order and perfectionism with high levels of self-demand projected also to others, rigidity in attitudes and behavior to cover up a great insecurity. Immanuel Kant had an ananchastic personality, always obsessed with schedules and all kinds of details regarding his health; he never wanted to change his daily routines; his punctuality was proverbial; on his evening walks he always breathed through his nose; his rigid sense of duty was also projected onto the categorical imperative of the Critique of Practical Reason.
