“You couldn't changed history. But you could get it right to start with. Do something differently the FIRST time around.This whole business with seeking Slytherin's secrets... seemed an awful lot like the sort of thing where, years later, you would look back and say, 'And THAT was where it all started to go wrong.'And he would wish desperately for the ability to fall back through time and make a different choice. Wish granted. Now what?”
“...To free humanity of time. For time is the great enslaver of us all. Time that ages us, time that limits us. Think how often you have wished to have more time for something, or wished you could go back a day and do something differently. When humanity is freed of time, old wrongs can be corrected before they are done.”
“There are times when I wish I could go back and change the course of my life. Make different choices...But the past cannot be changed, and we carry our choices with us, forward, into the unknown. We can only move on. Do you remember that I told you that at Spence?”
“It was from feeling oneself that one had reached the last barrier, that it was horrible, but that it could not be otherwise; that there was no escape for you; that you never could become a different man; that even if time and faith were still left you to change into something different you would most likely not wish to change; or if you did wish to, even then you would do nothing; because perhaps in reality there was nothing for you to change into.”
“A world of "if"s, but it would make no difference. If I could go back in time... but I couldn't. The past was behind me. The best thing now would be to stop looking over my shoulder. It was time to forget the past and look to the present and future.”
