Of Set Theory and Nested Hierarchies
Carl Linnaeus- 1707- 1778- Nested Hierarchy Classification
Georg Cantor- 1845-1918- Set Theory
Strange, Linnaeus developed his nested hierarchy classification without Cantor's set theory. Geez it looks like I am correct again- ie we don't need set theory to discuss nested hierarchies.
And not only that what is in the nested hierarchy is very important.
Great, Jon F chimes in:
Of course we don’t need set theory to discuss nested hierarchies, but it is applicable and useful.
Obvioulsy it isn't of any use nor is it applicable. Linnaeus didn't need it.
