In Nietzsche’s essay An Attempt at Self-Criticism (section 2) we can find the following quote:
The problem of science cannot be recognized within the context of science.
Nietzsche
How similar to Einstein’s better known (and much later) quote:
We cannot solve our problems with the same thinking we used when we created them.
Einstein
To have a chance at solving our difficult problems (whether they be artistic, scientific, ethical, or political), we must consider stepping outside our boundaries.
