Consider the following scenario. Julieis 300 feet away from her friend's front porch and observes, "Someone is sitting on the porch."
Given that she did not specify otherwise, we would assume that the someone Julie thinks she sees is a human. We
cannot guarantee thatJulie's observational statement is true. It could be that Julie's friend has something on the porch
that merely looks like a human from far away. Julie assumes she is correct and moves closer to see if she can figure out
whoitis. As she nears the porch, she declares, "Ah, it is our friend, John Berry."
