Eros is one of the three classical "types" of love; the term is used to refer to an intense or passionate desire (sometimes sexual) for a particular thing or person. Plato argued that, in doing so, what was sought was transcendental beauty, and that thetrefore the desire could not, in fact, be satisfied during life. Some Platonians argued that, since physical desire is something shared with the animal kingdom, and accordingly of a lower order, eros was ipso facto something more than this. Love, they said, was more than mere desire. Exactly what was a matter of debate for them.
