Abstractness

However, this solution was imperfect as it lacked the original abstractness.

The abstractness is harnessed in the game by having the deck produce random terrain, and chances to fire, and the like, simulating uncertainty as to the local conditions (nature of the terrain, etc.).

There is a scientific (exact) philosophy and theology, which deals with concepts of the highest abstractness; and this is also most highly fruitful for science.

Various attempts were made to substantiate the "abstract idea" test, which suffers from abstractness itself, but eventually none of them was successful.
