"From a drop of water a logician could infer the possibility of an Atlantic or a Niagara without having seen or heard of one or the other"

This quote by Arthur Conan Doyle talks to the power of reasoning and reduction. It suggests that a logician can utilize the information they need to reason about the world around them, even if they have never ever seen or heard of the important things in question. For instance, a logician might utilize the reality that they understand what a drop of water is to presume the possibility of an Atlantic or Niagara, 2 big bodies of water, without ever having seen or become aware of them. This quote speaks to the power of reasoning and reduction, and how it can be utilized to draw conclusions about the world around us, even if we have never ever seen or become aware of the important things in concern. It also speaks with the power of the human mind and its ability to make connections and draw conclusions from the details it has. Ultimately, this quote is a testimony to the power of reasoning and reduction, and how it can be utilized to make sense of the world around us.
