Joseph, the world is too diverse to press every object into a rigid category, and to find sharp 
definition boundaries. We need to let categories overlap.

Andy's garden pond is a good example. Everybody agrees that it's a pond, but when we have larger 
objects, the boundaries begin to blur, until we reach an object where everybody agrees that it is 
not a pond at all, it must be a lake.

Thus the objects will be mapped according to the subjective perception, but statistically objects 
like Andy's garden feature end on the pond side of the scale and the Werbellinsee on the lake side.

It's like trying to define a temperature value for 'hot' and 'cold':
For every human -10°C is cold and 45°C is hot, but at 20°C some go in a T-Shirt while others look 
for the woolen jumper.

Against deprecation of 'pond'.
