It is a peculiarity of man that he can only live by looking to the future -- sub specie aeternitatis. And this is his salvation in the most difficult moments of his existence, although he sometimes has to force his mind to the task.
I remember a personal experience. Almost in tears from pain (I had terrible sores on my feet from wearing torn shoes), I limped a few kilometers with our long column of men from the camp to our work site. Very cold, bitter winds struck us. I kept thinking of the endless little problems of our miserable life. What would there be to eat tonight? If a piece of sausage came as extra ration, should I exchange it for a piece of bread? Should I trade my last cigarette, which was left from a bonus I received a fortnight ago, for a bowl of soup? How could I get a piece of wire to replace the fragment which served as one of my shoelaces?...
I became disgusted with the state of affairs which compelled me, daily and hourly, to think of only such trivial things. I forced my thoughts to turn to another subject. Suddenly I saw myself standing on the platform of a well-lit, warm and pleasant lecture room. In front of me sat an attentive audience on comfortable upholstered seats. I was giving a lecture on the psychology of the concentration camp! All that oppressed me at that moment became objective, seen and described from the remote viewpoint of science.
By this method I succeeded somehow in rising above the situation, above the sufferings of the moment, and I observed them as if they were already of the past. Both I and my troubles became the object of an interesting psychoscientific study undertaken by myself. What does Spinoza say in his Ethics? -- "Affectus, qui passio est, desinit esse passio simulatque eius claram et distinctam formamus ideam." Emotion, which is suffering, ceases to be suffering as soon as we form a clear and precise picture of it.
The prisoner who had lost faith in the future -- his future -- was doomed. With his loss of belief in the future, he also lost his spiritual hold; he let himself decline and became subject to mental and physical decay. - Viktor Frankl Man's Search for Meaning
