 [t]hey are bound up with one another, unconnected as they may seem. Widely different though they are, the two of them march in unison like a prisoner and the escort he is handcuffed to. Fear keeps pace with hope. Nor does their so moving together surprise me; both belong to a mind in suspense, to a mind in a state of anxiety through looking into the future. Both are mainly due to projecting our thoughts far ahead of us instead of adapting ourselves to the present. (Seneca, Letter 5.7–8; in: 1969: 38)
