Fictionalists say 2+2=4 is true in the way that 'Oliver Twist lived in London' is true [Field,H]
|
|
Full Idea:
The fictionalist can say that the sense in which '2+2=4' is true is pretty much the same as the sense in which 'Oliver Twist lived in London' is true. They are true 'according to a well-known story', or 'according to standard mathematics'.

A reaction:
The roots of this idea are in Carnap. Fictionalism strikes me as brilliant, but poisonous in large doses. Novels can aspire to artistic truth, or to documentary truth. We invent a fiction, and nudge it slowly towards reality.

Intellectual and moral states, and even the soul itself, depend on prime matter for their existence [Blasius, by Pasnau]
|
|
Full Idea:
Blasius argued that prime matter is the subject of all our intellectual and moral states. This implies that such states cannot exist apart from the body, which seems to imply further that the soul itself cannot exist apart from the body.

From:
report of Blasius of Parma (Les quaestiones de anima (lectures on the soul) [1385], I.8 p.65) by Robert Pasnau - Metaphysical Themes 1274-1671 06.3
|
|
A reaction:
It seems that, under pressure, Blasius recanted this view in lectures given eleven years later.
