 Speculating on the historical development of the idea that all persons as such deserve respect, and using terms found in Kant’s writings on Achtung (the German word usually translated as “respect”), Feinberg (1975) identifies three concepts for which “respect” has been the name. (1) Respekt, is the “uneasy and watchful attitude that has ‘the element of fear’ in it” (1975, 1). Its objects are dangerous or powerful things. It is respekt that woodworkers are encouraged to have for power tools, a new sailor might be admonished to have for the sea, and a child might have for an abusive parent. Respekt contrasts with contemptuous disregard; it is shown in conduct that is cautious, self-protective, other-placating. (2) The second concept, observantia, is the moralized analogue of respekt. It involves regarding the object as making a rightful claim on our conduct, as deserving moral consideration in its own right, independently of considerations of personal well-being. It is observantia, Feinberg maintains, that historically was extended first to classes of non-dangerous but otherwise worthy people and then to all persons as such, regardless of merit or ability. Observantia encompasses both the respect said to be owed to all humans equally and the forms of polite respect and deference that acknowledge different social positions. On Kant’s account, observantia is the kind of respect we have an inviolable moral duty to give every person, both by acknowledging their claim to moral equality with us and by never treating persons as if they have little or no worth compared with ourselves (Kant 1797, 6:499). (3) Reverentia, the third concept, is the special feeling of profound awe and respect we involuntarily experience in the presence of something extraordinary or sublime, a feeling that both humbles and uplifts us. On Kant’s account, the moral law and people who exemplify it in morally worthy actions elicit reverentia from us, for we experience the law or its exemplification as “something that always trumps our inclinations in determining our wills” (Feinberg 1975, 2). Feinberg sees different forms of power as underlying the three kinds of respect; in each case, respect is the acknowledgment of the power of something other than ourselves to demand, command, or make claims on our attention, consideration, and deference.
