Are disposition ascriptions analysable via relevant implications? Florian Fischer University of Bonn
[Prior 1985]
„What is commonly accepted by all those who discussdispositions is that there exists a conceptual connectionbetween a statement attributing a disposition to an item and aparticular conditional. The acceptance of the existence of thisconceptual connection is a pre-theoretic common ground.“

„[T]o say that dispositions and conditionals are linked bynecessary biconditionals is not yet to endorse a reduction ineither direction.“

(Fink)The conditions for gaining (or loosing) a disposition are thesame as the stimulus condition C for that specific disposition.
[Lewis 1997]
„Something x is disposed at time t to give response r tostimulus s iff, for some intrinsic property B that x has at t, forsome time t’ after t, if x were to undergo stimulus s at time t andretain property B until t’, s and x’s having B would jointly be anx-complete cause of x’s giving response r.“
Marc Johnston & Alexander Bird
(Mask / Antidote)The manifestation of can be prevented although the stimulusand the disposition are present.
[Schrenk 2010]
„“[I]f this counterexample [antidote] works then it shows enpassant that metaphysical necessity can hardly be the drivingforce behind dispositional powers.” “
Malzkorn’s adequacy conditions
1. The basic disposition concepts are time dependent.
2. The analysans of an disposition must not imply that C or M areactually realized at the time of the ascription of dynM.C.
3. The analysans of an disposition must not imply that an objectcan not have dynM.C, if it shows the according manifestation.
4. The analysans of an disposition must not imply that themanifestation can not show itself for other reasons.
5. Dispositions are causal properties.
6. Dispositions are first order properties.

Situated inference„[A]n implication, A B, is true in a part of the world if there isinformation in that situation that tells us that if A is true in somepart of the world, then B is also true in some part of the world.These parts of the world are situations.“
A → B is true at a situations if and only if for all situations xand y if Rsxy and A is true at x, then B is true at y.
