Knowing and feeling are two different things, and feeling is what counts.
Sometimes happiness is not knowing the whole story.
It's one thing thinking something and another thing knowing it.
The basic mistake people make is to think that happiness is the goal!
Eros is not tranquil-it gives us spikes of happiness rather than a constant feeling of wellbeing. It's the love we feel at the beginning of a love affair and corresponds to the expression 'falling in love' since it is as involuntary an impulse as a physical fall.
