Questões de Vestibular USP 2018 para Vestibular - Primeira Fase

I. Cinquenta anos! Não era preciso confessá‐lo. Já se vai sentindo que o meu estilo não é tão lesto* como nos primeiros dias. Naquela ocasião, cessado o diálogo com o oficial da marinha, que enfiou a capa e saiu, confesso que fiquei um pouco triste. Voltei à sala, lembrou‐me dançar uma polca, embriagar‐ me das luzes, das flores, dos cristais, dos olhos bonitos, e do burburinho surdo e ligeiro das conversas particulares. E não me arrependo; remocei. Mas, meia hora depois, quando me retirei do baile, às quatro da manhã, o que é que fui achar no fundo do carro? Os meus cinquenta anos.

II. Meu caro crítico,

     Algumas páginas atrás, dizendo eu que tinha cinquenta anos, acrescentei: “Já se vai sentindo que o meu estilo não é tão lesto como nos primeiros dias”. Talvez aches esta frase incompreensível, sabendo‐se o meu atual estado; mas eu chamo a tua atenção para a sutileza daquele pensamento. O que eu quero dizer não é que esteja agora mais velho do que quando comecei o livro. A morte não envelhece. Quero dizer, sim, que em cada fase da narração da minha vida experimento a sensação correspondente. Valha‐me Deus! é preciso explicar tudo.

      What time isit? Thatsimple question probably is asked more often today than ever. In our clock‐studded, cell‐phone society, the answer is never more than a glance away, and so we can blissfully partition our daysinto eversmaller incrementsfor ever more tightly scheduled tasks, confident that we will always know it is 7:03 P.M.

      Modern scientific revelations about time, however, make the question endlessly frustrating. If we seek a precise knowledge of the time, the elusive infinitesimal of “now” dissolves into a scattering flock of nanoseconds. Bound by the speed of light and the velocity of nerve impulses, our perceptions of the present sketch the world as it was an instant ago—for all that our consciousness pretends otherwise, we can never catch up.

      Even in principle, perfect synchronicity escapes us. Relativity dictates that, like a strange syrup, time flows slower on moving trains than in the stations and faster in the mountains than in the valleys. The time for our wristwatch or digital screen is not exactly the same as the time for our head.  

      Our intuitions are deeply paradoxical. Time heals all wounds, but it is also the great destroyer. Time is relative but also relentless. There is time for every purpose under heaven, but there is never enough.
