 Both of these conditions for novelty have been questioned. Given the Independence Condition, it is unclear that any observational result O will count as novel for any theory, for it may always be true that the logically weakest set of premises that entail T (which will be cited in a minimally adequate reconstruction of the reasoning that led to T) will include O as a disjunct of one of the premises (Healey 2001: 779). The Uniqueness Condition insists that there be no available alternative explanation of O at the time T first explains O—but clearly, theories that explain O could be subsequently proposed and would threaten the imputation of truth to T no less. This condition seems arbitrarily to privilege theories depending on when they were proposed (Sarkar 1998: 206–8; Ladyman 1999: 184).
