‘Space’ is quite an abstract concept. It tells us ‘where’ or ‘how far’.

  • With ‘where’ we mean locations or positions that make up space.
  • With ‘how far’ we mean distance or displacement; the space from one position to a new.

Generally, space seems to be about positions. We wouldn’t say ‘what space is it?’ but rather ‘what position is it at?’. ‘Position’ seems to represent space in a tangible way. Let’s call it a property of space.1

With time and quantity,

  • we can say ‘what moment is it?’, but it of course also works to say ‘what time is it?’,
  • and we can say ‘how many are there?’ but actually also ‘what quantity is it?’.

It seems to work fine for time and quantity. So, let’s not rename them but simply call them properties along with position. These three properties define the concepts of time, quantity and space, so that we are able to talk about them and work with them.
