Single Idea 19268

[filed under theme 10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / c. Possible but inconceivable ]

Full Idea

If we aim to derive impossibility from inconceivability, we may either face a failure to conceive something, or arrive at a state of incoherence in conceiving.

Gist of Idea

Inconceivability (implying impossibility) may be failure to conceive, or incoherence

A Reaction

[summary] Thus I can't manage to conceive a multi-dimensional hypercube, but I don't even try to conceive a circular square. In both cases, we must consider whether the inconceivability results from our own inadequacy, rather than from the facts.


The 8 ideas from 'Understanding and Essence'

If 2-D conceivability can a priori show possibilities, this is a defence of conceptual analysis [Vaidya]
Define conceivable; how reliable is it; does inconceivability help; and what type of possibility results? [Vaidya]
Inconceivability (implying impossibility) may be failure to conceive, or incoherence [Vaidya]
In a disjunctive case, the justification comes from one side, and the truth from the other [Vaidya]
Gettier deductive justifications split the justification from the truthmaker [Vaidya]
Essential properties are necessary, but necessary properties may not be essential [Vaidya]
Aboutness is always intended, and cannot be accidental [Vaidya]
Can you possess objective understanding without realising it? [Vaidya]
