Quote by Ludwig Wittgenstein
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).
Summary
This quote suggests that to define boundaries or limits to our thoughts, we would need to be able to imagine both sides of those limits, even if they may seem unimaginable. It implies that in order to establish a restriction on our thinking, we must be capable of contemplating and comprehending ideas that are beyond the realm of our current understanding or thoughts. It highlights the paradoxical nature of attempting to define and limit our thoughts, as doing so necessitates exploring the very concepts that defy our present cognitive capacities.
