I'm not stuck on semantics, so that's the truth of the matter, whether you attempt to rationalize I am or not. Make no mistake that semantics are always important. Without the English language, neither you or I could communicate concepts here. It also allows you to attempt to reword what others are saying, but I'm not going to allow that here.

When you attempt to state someone is "stuck on semantics" and that person actually hasn't said as much, you are speaking for their intent. When that is backed up with the intent of proving them wrong on some topic, it only serves to indicate intent. The older I get, the more irritating this behavior becomes, especially when the person refuses to acknowledge what is being said and continues to rationalize from their point of view in order to frame a statement by someone else. You act as if language (and semantics) are logical. They aren't, and neither are humans. We'd do well to stop speaking for each other in aggregate in an attempt to make it more logical. This concept itself is counterintuitive.

Newton had every choice to pursue interests. Not having prior knowledge of "areas of discovery", it would appear he pursued what was interesting to him. If you look at Faraday, he pursued things to find a single source force - I would expect Newton though along the same lines. In fact, even if he knew someone else was interested in an "area of discovery", he could have just been interested in that topic for purely knowing purposes.

Wanting to know more about things, the nature of things if you will, is not something that can be considered a "bet". It's simply curiosity.
