The following is a straightforward corollary of Assertion 1.
Proof It is a straightforward consequence of the assertion (5) of Proposition 2.1 applied for x and x + y.
Therefore, ψ(x) = aφ(x) + b for all x ∈ I. Since ψ is non-constant, it follows that a ≠ 0. The reverse assertion is straightforward.
The proof of the remaining assertions is straightforward.
(For further discussion of this issue, see Crooke (2002).) The question of whether Blockhead is intelligent (has a mind, thinks) may seem straightforward, but despite Block's confident assertion that Blockhead "has all of the intelligence of a toaster"—it is not completely obvious that we should deny that Blockhead is intelligent.
