What is reality? Well, it’s the world around us, our environment, you´ll probably say, what else? But it’s not that easy. If you place two people next to each other, even with the same cultural background, in the same surroundings, they do not see the same reality. The difference is of course even greater with people of very diverse origins. Not to mention if you ask what the moose sees, or the wolf, or the lion, the owl, -or the moth! We all live in the same world, but experience it as if we were residents of different planets.
Another factor that governs our lives more than anything else, is time. In the human world, time is linear. For us, the future is fora short moment the present, before it is transformed into the past, and thereby turns into the history of our life. In nature, time is in many ways perceived as an everlasting, repeating cycle, in which one year passes into the other without any major changes.
These are existential considerations that have occupied the minds of philosophers from ancient times. Heidegger describes this essence of reality as Sein und Zeit, or “being and time”, and these thoughts were a  foundation for existentialism in philosophy. Today, existence and time are more important than ever as variables in our lives. Just during the last century, man has gone from being a species that led its life in fairly good interaction and cooperation with nature, to become a creature that has taken over the globe to an excessive degree and who always puts himself in the first row. Many, or should we say most, people of today have removed themselves so far from their roots that they consider nature as an abstract setting that has nothing to do with their lives.
