In this excerpt from A Christmas Carol by Charles Dickens, which two sentences suggest that people can alter their future by adjusting their present course? Scrooge crept towards it, trembling as he went; and following the finger, read upon the stone of the neglected grave his own name, Ebenezer Scrooge.

"Am I that man who lay upon the bed?" he cried, upon his knees.

The finger pointed from the grave to him, and back again.

"No, Spirit! Oh no, no!"

The finger still was there.

"Spirit!" he cried, tight clutching at its robe, "hear me! I am not the man I was. I will not be the man I must have been but for this intercourse. Why show me this, if I am past all hope!"

For the first time the hand appeared to shake.

"Good Spirit," he pursued, as down upon the ground he fell before it: "Your nature intercedes for me, and pities me. Assure me that I yet may change these shadows you have shown me, by an altered life!"

The kind hand trembled.

"I will honour Christmas in my heart, and try to keep it all the year. I will live in the Past, the Present, and the Future. The Spirits of all Three shall strive within me. I will not shut out the lessons that they teach. Oh, tell me I may sponge away the writing on this stone!"

In his agony, he caught the spectral hand. It sought to free itself, but he was strong in his entreaty, and detained it. The Spirit, stronger yet, repulsed him.
