Writing is also an art, Nandu. Note the title of this thread!
I'm of the mind that everything we do is based on emotion, and there is a certain amount of emotion in all our actions. You can't eliminate it.There are episodes of Star Trek, Nandu, where Spock's emotions do dictate his actions. Afterwards, he does what we all do; justify them 'logically.'
I tell my students this: Use your emotions, don't be used by them. There's a threshold past which your emotions are in charge and that can be like driving without brakes... blindfolded... with a stuck accelerator.
This is a writer's medium. If one cares about what is being discussed, as far as I'm concerned, one's posts should be carefully crafted, not only to express what is desired, but also in terms of how the reader may hear one's voice. Is meaning and intention important?
On the other hand, we have to read other's posts bearing in mind that the homunculi we have in our heads of each other are all, to some degree, inaccurate. We all form views and opinions of each other, and paint our homunculi accordingly. That sets up, if one isn't mindful, an automatic bias. We all do this. Myself included.
The only way to counter that is to treat each post as mindfully as we write our own. Don't read more than is there. If there is an urge to do so, there may very well be something there, but that's where questions come in handy and where assumptions can take a thread south.
You can't disassociate reason and emotion. But you can reach a point of maximum objectivity which, of course, isn't pure. Can't be. One of Terry Pratchett's characters, Tiffany Aching, has this to say about thoughts:
"First thoughts are the everyday thoughts. Second thoughts are the thoughts you think about the way you think. Third thoughts are thoughts that watch the world and think all by themselves."
Second thoughts (reminds me of metacognition) bring the higher order into the conversation.
Edit: I reread this a few minutes after posting and, in an attempt to practice what I preach, changed the pronouns in the 4th paragraph from 'you' and 'your' to the impersonal 'one' as I didn't want Nandu to think this was directed at him alone.
