explanandum

First, what is the explanandum? Second, what is the explanans?

Acknowledging the distinction problematizes both the explanandum of species cohesion and the explanans of gene flow that are central to the view discussed here.

The original explanandum was the appearance of contingency of necessary statements such as (1)-(4).

McGrath's explanation of (Success) runs into the kinds of difficulties described above, but it also involves another kind of mistake, the mistake of substituting an inappropriate paraphrase for the explanandum. (Success) is a generalization about entailment between propositions, and not the fact that true beliefs about our goals tend to facilitate success in achieving them.

The latter explanandum is properly addressed by describing the mechanism of heredity.

With respect to the question from where empirical evidence p derives, we are able to affirm that a fact is explained under the profile of the science when the assertion that describes it (the explanandum) is deduced from an explanans constituted by initial conditions or causes covered by universal laws.

But in that case judgements about the complexity of a purported explanans relative to its explanandum would be empirically justified; they could not be made a priori as Peacocke needs them to be.

First, the term here does not have its usual factive implication with respect to the explanandum. In asserting that <"Whales are fish" is true iff whales are fish> is an explanation of <"Whales are fish" is true>, the deflationist is not implying that "Whales are fish" is true.

In this way the explanandum is said to be rendered 'intelligible'; from the story we see how the events in question are possible .
