The later Wittgenstein, on the contrary, seems to have grown tired of serious thinking and to have invented a doctrine which would make such an activity unnecessary. I do not for one moment believe that the doctrine which has these lazy consequences is true. I realize, however, that I have an overpoweringly strong bias against it, for, if it is true, philosophy is, at best, a slight help to lexicographers, and at worst, an idle tea-table amusement.

“O Wittgenstein tardio… parece ter-se tornado cansado do pensamento sério e ter inventado uma doutrina que faria uma tal actividade desnecessária. Eu não acredito por um momento que a doutrina que tem estas consequências preguiçosas seja verdade. Compreendo, no entanto, que tenho um preconceito intensamente forte contra ele pois se é certo, filosofia é, na melhor das hipóteses, uma pequena ajuda para lexicógrafos e, na pior das hipóteses, um chá ocioso em mesa de diversão.”
