Is Russell aligned with Ludwig Wittgenstein’s statement, "The limits of my language mean the limits of my world."? Is he talking about how to communicate his world to others, or is he saying that without language internal reasoning is impossible?
Practically, I think the origins of fire-making abilities in humans tend to undermine that viewpoint. No other species is capable of reliably starting a fire with a few simple tools, yet the earliest archaeological evidence for fire (1 mya) could mean the ability predated complex linguistic capabilities. Observation and imitation could be enough for transmitting the skill from the first proto-human who successfully accomplished the task to others.
P.S. This is also why Homo sapiens should be renamed Homo ignis IMO.
