In this quote, Anthony Trollope is expressing the concept that life does not constantly follow the rules and expectations that are laid out in theories. Theories are typically based upon reasoning and thinking, however life is full of unpredictable events and emotions that can not constantly be explained or understood. Trollope is suggesting that while theories may offer a structure for understanding the world, they are not constantly suitable to the complexities of real life. This quote highlights the contrast between the idealized principles of theory and the unpleasant, unpredictable nature of life. It serves as a tip to not rely too greatly on theories and to welcome the unanticipated and imperfect nature of life.
"Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday"
