Yes. When he only swam halfway downstream. You do realize your philosophical ramblings are not being considered as serious dialogue.
You are twisting what I am saying to make them appear in your mind as ramblings. The salmon did not always swim upstream to spawn, this behaviour developed over millions and millions of years. There must have been a point when the salmon only swam halfway upstream "to spawn." Since I omitted the purpose of the upstream swim and you could not divine this purpose since it was so covertly hidden, I mention it now. The salmon in question is not just out for an afternoon swim, it's on a mission.
