Your comment adds nothing to the discussion, reveals your prejudice against social science, and could be copied and pasted anytime a non-rigorous subject comes up. I'm actually interested in criticisms of this work, but your comment doesn't even rise to that level.
But Bohm's "On Creativity", to me presents a much deeper "philosophical" take on a) what is creativity and b) how to foster it. And I dont see it referenced in this text at all.
Again, since this is about persuation, it is what the reader wants to believe.
There are (probably) several billion works on creativity. Just reading and listing your own sources of inspiration on creativity is quite the endheavor. And that is not going to be exhaustive even in a PhD thesis. I'll give leaway there - on the contrary, mine THEIR list for stuff I missed.
fair take, but my view these days is the following.
there is way too much information-garbage floating around.
hence I try to stick to time-tested classics particularly when it comes to certain topics. now, your time-tested classic may be different from mine and certainly, i want to see if there are things I missed, and hence I mentioned Bohm's work, as something the author of this PhD missed.
End of the day, there are many belief systems that we human hold onto, but we need a method to settle opinion.
And science happens to be a certain kind of a method for settling opinion.
CS Peirce wrote about it so beautifully in his 1877 essay: "On the fixation of belief". go read it. here is a link saving you a google search. https://www.peirce.org/writings/p107.html
