| 5.1.1  | ITS WIDTH
        AND DEPTH | 
    Suppose  you know about the existence of a certain office
 for clerical or administrative work and you also know (or would
 expect it)  that that office employs,  and always has employed,
 people of  different heights:  short,  medium  and  tall.  Now,
 imagine that someone comes up to you and begins to tell you that
 all short  people  working  at  that  office  lost  their  jobs.
 Probably you would,  then,  wonder why the firm in question only
 sent, or had to send, the short workers  away,  and  what  their
 height has to do with it.  But  how come?  Your informant never
 told you  that those workers who are  not  short  did  not  lose
 their jobs.  That  is what you made up yourself.  As a matter of
 fact  (in our imaginary case)  the  office  had  to close down
 (because the firm went bankrupt, say, or because the government
 thought the firm had become superfluous),  and  that is why all
 the workers were sacked as redundant regardless of their height.
 (They  may  or  they may not have got another job right away.)
 Hence, all short bodies were laid off,  but also the medium ones
 and the tall ones.
 Your informant did tell you the truth,
 altho
 it was in telling you the truth that
 'e made a distinction which
 was not relevant.
 In
 'er statement 'e distinguished workers
 who are short from those who are not, and this distinction was not
 relevant, firstly, because a person's height is (supposedly) not relevant
 with respect to clerical and administrative  work, and secondly, it was
 not even judged relevant in the case of the workers' dismissal.
 What  you  rightly  assumed  is  that  your
 informant would not only tell you the truth,  but  that 'e would
 also  make  only  relevant  (or perhaps  potentially relevant)
 distinctions when telling you the truth. With this assumption it
 was a so-called 'conversational implicature' that only the short
 workers would have lost their jobs.
    Suppose that the office in the above example does not have to
 close  down,  that  they  are  even  expanding,  but  that  they
 exclusively hire medium short and short people. In spite of this
 a person's height remains irrelevant with respect to the kind of
 office  work  to  be done (and also the premises themselves can
 handle bodies of widely divergent heights).  The office may now
 be blamed for discriminating on the grounds of people's  height,
 an irrelevant, bodily property in this context. But imagine that
 the management of  that  office  reply  that  there  is  nothing
 wrong  with  discrimination,  that  our  whole life is only made
 possible  by  virtue  of  the  distinctions  we  make.  This  is
 certainly  true,  but  the management hope that we do not notice
 that they commit a fallacy of equivocation: they are not blamed
 for making a distinction but for making an irrelevant distinction.
 (Compare  the distinction made between people who are, or
 were, employed at the office and people who are, or  were,  not.
 This distinction we accept in the informant's statement, yet not
 that between workers who are short and those who are not.)
   In  the  language which is our present means of communication
 both making distinctions and discrimination have two basic
 meanings which must not be confused. Firstly, they have a
 nonpejorative, often meliorative, formal meaning, namely:
 distinguishing by discerning or exposing differences, especially when
 distinguishing one object from another; or: making an appropriate
 distinction.  In  this  sense of the word,  everyone has to
 discriminate. It is an ontological and epistemological prerequisite
 of all thought. To discriminate also means to use good
 judgment, and some people do know how to thus 'discriminate'
 between real and pretended cases of concern for their well-being.
 Other  people  may  'show fine discrimination'  in  only
 picking out those works of art which are genuine.  But secondly,
 making distinctions and discrimination have a pejorative,
 or rather condemnatory meaning not restricted to the formal
 register, namely: making an irrelevant or unjustified distinction;
 making  a difference in treatment or favor on a basis other than
 individual merit. This is the meaning discrimination has when
 someone is accused of, for example, 'sex discrimination'.
 In
 practise people
 tend to speak of "discrimination" particularly when the irrelevant
 distinction is made in
 nonpropositional reality itself.
 Some might say that the employer who makes a distinction between workers
 who are tall and workers who are not, while height is irrelevant,
 'discriminates', that is, against the one group and/or in favor of the
 other, whereas the informant who made an equally irrelevant distinction
 between workers who are short and workers who are not, did not
 'discriminate'.
 The former distinction is made in nonpropositional reality
 itself and, moreover, harms a category of people distinguished
 on the basis of their height (namely tall people); the
 latter one  is only made in a proposition about reality  and the
 person who probably will be harmed most is  the person receiving
 the (irrelevant) information.  However, rather than limiting the
 use of the term discrimination to specific cases (which is
 etymologically not justifiable)  we  ourselves  shall  put  the
 emphasis on the kinds of relevancy involved. When it is the relevancy
 of a distinction, we shall speak of "discriminational
 relevancy". The relevancy which plays such an important role
 in all our conversation (in addition to truth) we shall call
 "conversational relevancy". This subdivision of relevancy is
 part of a provisional scheme  which  does not preclude  that one
 type of relevancy consists of  two or more independent subtypes,
 or that one type is a subtype of the other.
    The study of relevancy in general has both a horizontal and a
 vertical dimension, as indicated in
 figure I.5.1.1.1. The
 horizontal dimension concerns the 'width' of the notion of
 relevancy,  that  is,  the  different  kinds  of  relevancy  and
 related notions prevailing in several fields of thought. In this
 and  the next  division  we will  look at  the similarities  and
 differences in meaning and use of all these types of relevancy.
 Our prime interest  will then be  what bearing this has on
 the notion of discriminational relevancy.  We will even  discuss
 —albeit only briefly— a number  of  notions  of relevancy or
 relatedness which are apparently of an entirely different nature
 than discriminational relevancy. The reason for this is, firstly,
 that they are part of one and the same overall structure of
 relevancy notions,  and  secondly,  that  an analysis  of  these
 diverse conceptions  in  the horizontal dimension  of  relevancy
 will  enable  us  to  clear  up  the  workings  of  the numerous
 adjectives which go with relevancy.
 These adjectives and adverbs must somehow modify or typify what is
 denoted by the noun (ir)relevance and
 the adjective (ir)relevant.
 Unlike our discriminational, moral is one of those
 adjectives used, and frequently used, by ethical theorists.
 But the fate of morally relevant when trying to clarify the nature
 of morality with it, appears hardly any better than that of causally
 relevant when that notion is used in an (abortive) attempt to clarify
 the nature of causality.
    The vertical conceptual analysis of relevancy concerns
 the difference  between something  (a distinction, proposition,
 topic, and so on)  being  relevant,  and  it  being irrelevant.
 Relevant is then used in an affirmative sense as the negation
 of irrelevant.  Since relevant is an unmarked term
 (irrelevant being the marked one ), it has also a general,
 dimensional  meaning  designating  the  extension  of  both
 irrelevance and its negation. This is the meaning relevancy has
 when we speak of the different types of relevancy.  We shall use
 the noun relevancy only in this general, dimensional sense,
 and relevance only as the antonym of irrelevance,
 altho relevancy and relevance are synonyms in the traditional
 lexicon. As the core meaning of the marked term (discriminationally)
 irrelevant  we  will take  the meaning  it has  when
 discrimination in its condemnatory sense is defined as the
 act of making an irrelevant distinction. For example, racial
 discrimination is the  act (in a broader sense also practise or
 attitude) of making an irrelevant distinction on the grounds of
 race or skin color.  In  the event  that  a distinction  on  the
 grounds of race or skin color is relevant,  there is  no talk of
 discrimination in this respect and in this sense.
    What  are  the criterions  to  objectively determine  whether
 something is relevant or not?  This is the problem of relevancy
 in depth. We will consider one theory which furnishes criterions
 for telling the relevant apart from the irrelevant.  Dealing
 with statistical relevancy it is of limited use for discriminational
 relevancy  tho.  That is  why  we will eventually have to
 develop  our own  account  of  the relevance-irrelevance  divide
 which plays  such a crucial role in questions of discrimination.
 Yet, before doing so it will be worthwhile to have a look at the
 motley tissue of occurrences of the term relevant, not only in
 ethics and linguistic pragmatics but also in other disciplines.
