The real John Locke apparently had trouble walking too.
He was naturally very active, and employed himself as much as his health would permit. Sometimes he diverted himself with working in the garden, which he well understood. He loved walking, but not being able to walk much, through the disorder of his lungs, he used to ride out after dinner...
[I have to keep reminding myself that these "riding" philosophers were on horseback, not bikes. Philosophy Rides, the sequel, will not be a historical survey.]
His bad health was a disturbance to none but himself... his usual drink was nothing but water...Good for him, I guess. He's not the philosopher I'd most like to spend time in a pub with, though I admire his most pragmatic statement that "the actions of men [are] the best interpreters of their thought."
His near-dying words were that we should regard this world and life as nothing but a vanity and "a state of preparation for a better." Repugnant words, to a humanist. And yet, other words of his ("all mankind being equal and independent, none ought to harm another in his life, health, liberty") inspired some of our greatest social and political experiments.
And some of our strangest television. Don't tell me what I can't do.
