Chapter 7: I Learn My Neighbor’s Profession
Explanation and Analysis—Completely Unimportant:

In Chapter 7, Poirot and Sheppard examine the murder scene. Poirot uses logos to explain why he is interested in the odd positioning of a chair in the room, foreshadowing the way he will out-think Sheppard in the end:

“Raymond or Blunt must have pushed it back,” I suggested. “Surely it isn’t important?”

“It is completely unimportant,” said Poirot. “That is why it is so interesting,” he added softly.

Chapter 13: The Goose Quill
Explanation and Analysis—Too Many Motives:

In Chapter 13, Dr. Sheppard and Poirot discuss Ralph Paton's disappearance and his many motives for killing Roger Ackroyd. Poirot uses logos to challenge Sheppard's assertion that things are looking bad for Ralph:

“Dear me,” I said, rather taken aback. “The case does seem black against him.”

“Does it?” said Poirot. “That is where we disagree, you and I. Three motives—it is almost too much. I am inclined to believe that, after all, Ralph Paton is innocent.”
