Wittgenstein to me is mostly impossible to understand, but he says a lot of interesting things. I only don't want to spend more time with him to grasp what he intends to say. It comes down to the economy of time and your taste, I mean all your intellectual endevour in the humanities. The following are from Tractatus:
2.012 In logic nothing is accidental: if a thing CAN occur in a state of affairs, the possibility of the state of affairs must be written into the thing itself.
2.014 Objects contain the possibility of all situations.
Wittgenstein, Tractatus Logico-Philosophicus (1922)
These two bits match well with the premises of the concept of affordance.
