With an account, you can revise, criticize, and comment on ideas.Living according to reason and rationality alone is impossible, because propositional knowledge is only a subset of needed knowledge for an embodied agent (the others being procedural, participatory- and perspectival knowledge)
It sounds like you have a different conception of knowledge and rationality from Popper’s/Deutsch’s.
There’s a unity of knowledge. Knowledge isn’t fragmented the way you suggest. Rationality means finding common preferences among ideas, ie making different types of ideas jibe. Why should that not be possible for the types of knowledge you mention?
Even if knowledge is unified at some fundamental level, we might not be able to live by means of this unified knowledge alone (because of how we function or pure complexity). Living life might require operating through other «kinds» of knowledge which are pre- cognitive. You cannot ride a bike or maintain a relationship by thinking through quantum mechanical or propositional theories to word.

That isn’t what I mean by unity of knowledge. Of course we can’t process our knowledge in its totality at once. That’s necessarily piecemeal. But that doesn’t mean we can’t live a life guided by reason.
If you consider riding a bike an example of irrationality, and reasoning through quantum mechanics an example of rationality, then you haven’t understood Deutsch’s/my stance on rationality. I think you should study it, ask more questions about it, before you’re ready to criticize it.
After reading some more about Deutsch's and your definition of reason. Is it accurate to view reason more as a process than a static state? Where the process might be summed up by
1. Being open to criticism
2. Truth-seeking (commitment to getting ideas to jibe)
Thanks for asking good questions.
Is it accurate to view reason more as a process than a static state?
Yes.
Where the process might be summed up by
1. Being open to criticism
2. Truth-seeking (commitment to getting ideas to jibe)
Yes. Aka ‘common-preference finding’ aka ‘fun’.
Some of the virtues that @benjamin-davies has put together are part of it, too.
Interesting! Getting ideas to jibe/cohere seems like a more and more fundamental idea the more I think about it. Has anyone explored whether the collection of ideas in a person's mind must have a specific structure?
When discussing virtues, you seem to suggest a hierarchical organization of ideas, as opposed to ideas competing horizontally for attention and salience. It appears that ideas organize vertically in a hierarchy, where activating "higher-level" ideas automatically resolves conflicts among lower-level ones. For example, if a snake suddenly appears next to you, all previous internal conflicts dissolve because self-preservation is among the most dominant (highest) ideas in their value structure.
However, individuals can construct even higher-order values that override self-preservation. The structure seems hierarchical: when a top-level idea is activated, there seems to be some alignment in lower level ideas.
Getting ideas to jibe/cohere seems like a more and more fundamental idea the more I think about it.
Agreed. There’s more to it than meets the eye. For example, maybe capitalism can be thought of as society-wide common-preference finding (#3013). Rationality might work the same way across minds as it does within a single mind. Capitalism as an expression of rationality in society.
As for virtues, I think some virtues are more fundamental than others. There are some virtues I think people should adopt. Like, rationality depends on them. But the core functionality of the mind as a whole does not. There’s a difference between creativity and rationality. Which virtues someone adopts and why and how they prioritize them in different situations is downstream of creativity as a whole.
I don’t know if activating higher virtues always resolves conflicts between ideas. But it could put them on hold for a while, yeah. If I see a venomous snake, my main priority is to get to safety (life as the ultimate value, as objectivists would say).
