For Heidegger, boredom is a privileged fundamental mood because it leads us directly into the very problem complex of being and time.

~ Lars Fr. H. Svendsen

Man is a world-forming being, a being that actively constitutes his own world, but when everything is always already fully coded, the active constituting of the world is made superfluous, and we lose friction in relation to the world.We Romantics need a meaning that we ourselves realize – and the person who is preoccupied with self-realization inevitably has a meaning problem. This is no one collective meaning in life any more, a meaning that it is up to the individual to participate in. Nor is it that easy to find an own meaning in life, either. The meaning that most people embrace is self-realization as such, but it is not obvious what type of self is to be realized, nor whatshould possibly result from it. The person who is certain as regards himself will not ask the question as to who he is. Only a problematic self feels the need for realization.

~ Lars Fr. H. Svendsen

Animals can be understimulated, but hardly bored.

~ Lars Fr. H. Svendsen

One mood can be replaced by another, but it is impossible to leave attunement altogether. However, profound boredom brings us as close to a state of un-attunement as we can come.
