Rather than being a luxury, emotions are a very intelligent way of driving an organism toward certain outcomes.

Emotions are enmeshed in the neural networks of reason.

Imagine, for example, birds. When they look out at the world, they have a sense that they are alive. If they are in pain, they can do something about it. If they have hunger or thirst, they can satisfy that. It's this basic feeling that there is life ticking away inside of you.

Emotion is set in our genome and that we all have with a certain programmed nature that is modified by our experience so individually we have variations on the pattern. But in essence, your emotion of joy and mine are going to be extremely similar.

A conscious mind is a mind with a self in it.

The mechanism of primary emotions does not describe the full range of emotional behaviors. They are, to be sure, the basic mechanism. However, I believe that in terms of an individual's development they are followed by mechanisms of secondary emotions, which occur once we begin experiencing feelings and forming systematic connections between categories of objects and situations, on the one hand, and primary emotions, on the other.

You're not the same after, say, an incredible love affair that went very well or a love affair that went bad. Or something that happens to your health, or something that happened to somebody else's health, that is close to you. Or something that happens professionally.
