Elusive thoughts

Why did I not think of this before? I should have brought this up during that discussion! It would have been so useful. How many times does this happen to us?

Can a thought remain unnoticed as it blends with the "environment"  around it? Thoughts can be funny, hiding at times, when they would have been most welcome, and showing up when they are least expected. Can this be some sort of a camouflage effect? When the environment, that is your brain, is trying to think of something, do related thoughts camouflage and hence remain unnoticed? Do unrelated thoughts pop up only later?

Some times when you are trying to think hard about something, thoughts simply remain elusive and unnoticed, as they camouflage with the background. So the trick is to change the background quickly, and the thought will then be visible.

A Premise

Look for its definition in google dictionary and you will find,

 "A previous statement or proposition from which another is inferred or follows as a conclusion" 

"If you find a contradiction, then check your premises and one of them will be wrong."  Found this while reading "Atlas Shrugged " and this statement kept coming back to me.

How does one make a premise? Do we give enough thought before making one? Do we reason out enough before drawing conclusions? Well, not always. Every time we find a contradiction, for sure at least one of our initial or intermediate premises was incorrect. So I will now look to make my premises carefully to make sure that my conclusions have the least possible errors, and will find lesser contradictions. But if I am unable to ascertain the correctness of my premise, I will not look to draw a conclusion at all.
