moreThere has been a long dispute concerning the status of ethical sentences. Are they empirical or, if not, merely conventional? This question is important, because for instance from a ethical conventionalism a ethical relativism would follow challenging the whole concept of moral obligation.
Wittgenstein’s epistemological remarks help to understand the role of ethical sentences within our life.
In his Philosophical Investigations (PI) Wittgenstein claims that „the meaning of a word is its use in the language“ (PI §43). The word’s use emerges from the practice it is connected with within a language game (PI, §7). While they are doing certain things the language-gamers („as they go along“, PI, §83) invent concepts and also rules to use them correctly initially within primitive language games. Although these concepts are linked to the empirical world via the common practice, the use and therefore the meaning of the concepts itself are conventional. The meaning of ethical sentences or concepts also has its origin in such language games.
There are certain kinds of sentences. Empirical sentences (a) tell us something about the world. They can be doubted, validated, and in consequence turn out to be right or wrong. Distinct from empirical sentences are grammatical sentences (b) (Wittgenstein refers to them as „nonsens“). They explain how to use words correctly, like: „Every rod has a length“ (PI, §251). These sentences can neither be doubted nor validated nor turn out to be right or wrong. However, the point of On Certainty (OC) is that there are sentences (c) which can be formally doubted like „I have two hands“, but which, in fact, are never doubted, because it would be completely strange to do so. There is no reason to doubt these sentences. They are self-evident. Finally there are sentences (d) which are empirical, but haven’t been validated by the individual yet so that he believes them, because someone told him so or he learned them.
Especially c-, but also d-sentences constitute a world-picture. A world-picture is not true or false, because „I did not get my picture of the world by satisfying myself of its correctness; nor do I have it because I am satisfied of its correctness. No: it is the inherited background against which I distinguish between true and false“ (OC, §94). The sentences which constitute the world-picture „might be part of a kind of mythology“ (OC, §95). Thus, „an entire mythology is stored within or language“ (Remarks on Frazer’s Golden Bough, 133). Speaking a language therefore always means working on one’s world-picture – the way one sees the world.
I will argue that ethical sentences are no grammatical sentences (b) as it is possible to doubt them. But they are also no empirical sentences (a) as they do not tell us anything about the world (Lecture on Ethics)
As a subclass of (c) they constitute our world-picture und therefore the way we see the world and react to it. Though, ethics is less a system of prescriptions, but rather an constant struggle for how we want to live. In this sense Wittgenstein’s early comment: „The world of the happy man is a different one from that of the unhappy man“ (TLP, 6.43) becomes understandable.
