In Victor Hugo's "Les Miserables," revolution is equated with the concept of progress. It suggests that revolution is a necessary and constant movement toward advancement in society. This perspective presents revolution not merely as a drastic change, but as an essential part of evolving towards a better future.

The quote also emphasizes the idea of tomorrow as an embodiment of progress. Tomorrow symbolizes the inevitable advancement that shapes our lives today. It reinforces the notion that while change may be slow, it is continuously taking place and will ultimately drive society towards improvement.
