[filed under theme 18. Thought / A. Modes of Thought / 5. Rationality / a. Rationality ]

Full Idea

It would be a superhuman task just to write down an explicit, non-summary style, statement of the platitudes that capture our idea of what it is to be fully rational.

Gist of Idea

Capturing all the common sense facts about rationality is almost impossible

Source

Michael Smith (The Moral Problem [1994], 5.9)

Book Ref

Smith,Michael: 'The Moral Problem' [Blackwell 1994], p.163


A Reaction

Well said. Philosophers are inclined to make simplistic binary judgements about whether persons or animals are rational. A visit to YouTube will show fish acting extremely rationally.

The 20 ideas from Michael Smith

Analysis aims to express the full set of platitudes surrounding a given concept [Smith,M]
A pure desire could be criticised if it were based on a false belief [Smith,M]
In the Humean account, desires are not true/false, or subject to any rational criticism [Smith,M]
Expressivists count attitudes as 'moral' if they concern features of things, rather than their mere existence [Smith,M]
Moral internalism says a judgement of rightness is thereby motivating [Smith,M]
'Rationalism' says the rightness of an action is a reason to perform it [Smith,M]
'Externalists' say moral judgements are not reasons, and maybe not even motives [Smith,M]
A person could make a moral judgement without being in any way motivated by it [Smith,M]
Motivating reasons are psychological, while normative reasons are external [Smith,M]
Subjects may be fallible about the desires which explain their actions [Smith,M]
A person can have a desire without feeling it [Smith,M]
Humeans (unlike their opponents) say that desires and judgements can separate [Smith,M]
Goals need desires, and so only desires can motivate us [Smith,M]
Humeans take maximising desire satisfaction as the normative reasons for actions [Smith,M]
Is valuing something a matter of believing or a matter of desiring? [Smith,M]
If first- and second-order desires conflict, harmony does not require the second-order to win [Smith,M]
Objective reasons to act might be the systematic desires of a fully rational person [Smith,M]
Defining a set of things by paradigms doesn't pin them down enough [Smith,M]
Capturing all the common sense facts about rationality is almost impossible [Smith,M]
We cannot expect even fully rational people to converge on having the same desires for action [Smith,M]
