Hence also there can be no ethical propositions.

Propositions cannot express anything higher.

6.421    It is clear that ethics cannot be expressed.

Ethics is transcendental.

(Ethics and æsthetics are one.)

6.422    The first thought in setting up an ethical law of the form "thou shalt . . ." is: And what if I do not do it? But it is clear that ethics has nothing to do with punishment and reward in the ordinary sense. This question as to the consequences of an action must therefore be irrelevant. At least these consequences will not be events. For there must be something right in that formulation of the question. There must be some sort of ethical reward and ethical punishment, but this must lie in the action itself.

(And this is clear also that the reward must be something acceptable, and the punishment something unacceptable.)

6.423    Of the will as the subject of the ethical we cannot speak.

And the will as a phenomenon is only of interest to psychology.
