Unreflectively, we all assume there are nonexistents, and we can refer to them [Reimer]
|
|
Full Idea:
As speakers of the language, we unreflectively assume that there are nonexistents, and that reference to them is possible.

From:
Marga Reimer (The Problem of Empty Names [2001], p.499), quoted by Sarah Sawyer - Empty Names 4
|
|
A reaction:
Sarah Swoyer quotes this as a good solution to the problem of empty names, and I like it. It introduces a two-tier picture of our understanding of the world, as 'unreflective' and 'reflective', but that seems good. We accept numbers 'unreflectively'.

Motion is not absolute, but consists in relation [Leibniz]
|
|
Full Idea:
In reality motion is not something absolute, but consists in relation.
|
|
From:
Gottfried Leibniz (On Motion [1677], A6.4.1968), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3
|
|
A reaction:
It is often thought that motion being relative was invented by Einstein, but Leibniz wholeheartedly embraced 'Galilean relativity', and refused to even consider any absolute concept of motion. Acceleration is a bit trickier than velocity.
