Did the typewriter influence Nietzsche's philosophy?

Interesting thoughts here. Robert Hassan is not a philosophy professor, but one of communications, it should be noted. Nonetheless, he appears to have made some informed criticism about how adopting a modern (for his day) portable typewriter, by the different mechanics from pen and ink, and the different writing speed, may have influenced Nietzsche's thought process, and his thoughts.

That said, this is not implausible. Professors of literature, creative writing and psychology, along with those of neuroscience at times, talk about how journaling — when done with pen and ink — can have influence on our own mental attitudes.

Now, that means the question actually is, did it influence him THAT MUCH?

Here, I am at least moderately if not highly skeptical.

And, the idea that switching — albeit, a forced switch — from pen to typewriter "restructured his consciousness"? True, but in the sense of being a truism. ANYTHING we do restructures our consciousness, contra quasi-New Agers.

Beyond that, any change in Nietzsche's style of philosophizing may be correlational only, or correlational first, causal second. And, the growing tumor causing his growing blindness may have been the primary causal agent.
