Full Idea
The world is full of 'things' that it does not make sense to count as substances; for example: rumours, heatwaves, songs, headaches.
Gist of Idea
The world contains many 'things' which are not substances

A Reaction
Rescher, of course, prefers to think of them as 'processes'. The word 'process' strikes me as over-emphasising where it is going, at the expense of what it is. Songs and headaches are vivid in the moment, with their duration simply an extra feature.
