Um, I think that something was lost in the translation here.  
The limbic system does all the stuff I posted above all by itself. It’s functions are much older than the cortex and are vital to survival for all the “lower” lifeforms.  
The Papaz circuit loops in dozens of clusters of nerve bodies, each tuned up to do different things.

> The Papez circuit /peɪpz/, or medial limbic circuit, is a neural circuit for the control of emotional expression. In 1937, James Papez proposed that the circuit connecting the hypothalamus to the limbic lobe was the basis for emotional experiences. Paul D. MacLean reconceptualized Papez's proposal and coined the term limbic system. MacLean redefined the circuit as the "visceral brain" which consisted of the limbic lobe and its major connections in the forebrain – hypothalamus, amygdala, Recent s...

  
I have mentioned the amygdala but there are other important bits and pieces involved:

Each of these bits has bunches of sub-components - for example - the hypothalamus:

Back to the amygdala - it is also composed of lots of subsystems:

It’s tiny little projecting fibers go all over the place!

So all these emotions are not some little bit you learn - they are discrete chemical pathways that are learned as part of the mix of fibers feeding into the prefrontal cortex and the temporal lobe.

As you experience whatever it is that you experience the limbic system is adding it’s output to the other senses to be learned and remembered right alongside those other senses.

Remember - this is all before the cortex has anything to say about things.
