Thinking about how if you get to a toilet and the seat has piss on it, when you wipe the piss you’re actually just creating a very thin film of piss all around the seat, instead of a little splat in one area. A thin film which you then sit on.

The first moment—the moment of the understanding—is the moment of fixity, in which concepts or forms have a seemingly stable definition or determination

The second moment—the “dialectical” moment—is the moment of instability...the determination that was fixed in the first moment passes into its opposite. Hegel describes this process as a process of “self-sublation”... it means both to cancel (or negate) and to preserve at the same time. The moment of understanding sublates itself because its own character or nature—its one-sidedness or restrictedness—destabilizes its definition and leads it to pass into its opposite.

The third moment—the “speculative” or “positively rational” moment—grasps the unity of the opposition between the first two determinations, or is the positive result of the dissolution or transition of those determinations. Here, Hegel rejects the traditional, reductio ad absurdum argument, which says that when the premises of an argument lead to a contradiction, then the premises must be discarded altogether, leaving nothing. As Hegel suggests in the Phenomenology, such an argument:

"is just the skepticism which only ever sees pure nothingness in its result and abstracts from the fact that this nothingness is specifically the nothingness of that from which it results."

Although the speculative moment negates the contradiction, it is a determinate or defined nothingness because it is the result of a specific process.
