An ink bottle, which now seems impossibly quaint, was still thinkable as a symbol in 1970.

No possible future government in Kabul can be worse than the Taliban, and no thinkable future government would allow the level of Al Qaeda gangsterism to recur. So the outcome is proportionate and congruent with international principles of selfdefense.
christopher hitchensThe aim of the book is to set a limit to thought, or rather — not to thought, but to the expression of thoughts: for in order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought). It will therefore only be in language that the limit can be set, and what lies on the other side of the limit will simply be nonsense.
ludwig wittgensteinGeneral Systems Theory is a name which has come into use to describe a level of theoretical modelbuilding which lies somewhere between the highly generalized constructions of pure mathematics and the specific theories of the specialized disciplines. Mathematics attempts to organize highly general relationships into a coherent system, a system however which does not have any necessary connections with the "real" world around us. It studies all thinkable relationships abstracted from any concrete situation or body of empirical knowledge.
