Even if it were possible to cast my horoscope in this one life, and to make an accurate prediction about my future, it would not be possible to 'show' it to me because as soon as I saw it my future would change by definition. This is why Werner Heisenberg's adaptation of the Hays Office—the so-called principle of uncertainty whereby the act of measuring something has the effect of altering the measurement—is of such importance. In my case the difference is often made by publicity. For example, and to boast of one of my few virtues, I used to derive pleasure from giving my time to bright young people who showed promise as writers and who asked for my help. Then some profile of me quoted someone who disclosed that I liked to do this. Then it became something widely said of me, whereupon it became almost impossible for me to go on doing it, because I started to receive far more requests than I could respond to, let alone satisfy. Perception modifies reality: when I abandoned the smoking habit of more than three decades I was given a supposedly helpful pill called Wellbutrin. But as soon as I discovered that this was the brand name for an antidepressant, I tossed the bottle away. There may be successful methods for overcoming the blues but for me they cannot include a capsule that says: 'Fool yourself into happiness, while pretending not to do so.' I should actually want my mind to be strong enough to circumvent such a trick.
Many scientists have tried to make determinism and complementarity the basis of conclusions that seem to me weak and dangerous; for instance, they have used Heisenberg's uncertainty principle to bolster up human free will, though his principle, which applies exclusively to the behavior of electrons and is the direct result of microphysical measurement techniques, has nothing to do with human freedom of choice. It is far safer and wiser that the physicist remain on the solid ground of theoretical physics itself and eschew the shifting sands of philosophic extrapolations.
