Single Idea 14589

[filed under theme 10. Modality / A. Necessity / 11. Denial of Necessity ]

Full Idea

One person says 'He can't dig a hole; he hasn't got a spade', and another says 'He can dig a hole; just give him a spade', and both uses of the modal 'can' will be true. So some philosophers say that all modal predications are thus context-dependent.

Gist of Idea

A modal can reverse meaning if the context is seen differently, so maybe context is all?

A Reaction

Quine is the guru for this view of modality. Hawthorne's example seems to me to rely too much on the linguistic feature of contrasting 'can' and 'can't'. The underlying assertion in the propositions says something real about the possibilities.

The 17 ideas from John Hawthorne

14588 Modern metaphysicians tend to think space-time points are more fundamental than space-time regions [Hawthorne]
14589 A modal can reverse meaning if the context is seen differently, so maybe context is all? [Hawthorne]
14590 If we accept scattered objects such as archipelagos, why not think of cars that way? [Hawthorne]
14591 Four-dimensionalists say instantaneous objects are more fundamental than long-lived ones [Hawthorne]
19551 How can we know the heavyweight implications of normal knowledge? Must we distort 'knowledge'? [Hawthorne]
19552 We wouldn't know the logical implications of our knowledge if small risks added up to big risks [Hawthorne]
19554 Denying closure is denying we know P when we know P and Q, which is absurd in simple cases [Hawthorne]

15121 An individual essence is a necessary and sufficient profile for a thing [Hawthorne]
15123 Is the causal profile of a property its essence? [Hawthorne]
15122 Could two different properties have the same causal profile? [Hawthorne]
15124 If properties are more than their powers, we could have two properties with the same power [Hawthorne]
15126 Maybe scientific causation is just generalisation about the patterns [Hawthorne]
