Moving of th'earth brings harms and fears,
Lust is like an earthquake (or "moving of the earth"). It's a destructive force that attracts lots of attention and gets everyone riled up. Everyone is talking about the couple that's all over each other. That doesn't make it love.

Dull, sublunary lovers' love
This is the whole argument. Earthly lovers (who are really just lusting) only care about the senses—mainly touch. So when they have to part, they lose the only thing holding them together.
| Quote #3
Inter-assurèd of the mind,
Who needs lust when you have peace of mind and commitment in love? Not this couple, that's for sure.
