What is the rhetrical device f the underlined sentence?
Never cncerned that the answer may let us dwn, with pleasure and cnfidence we turn ver each new stne t find unimagined strangeness leading n t mre wnderful questins and mysteries.
It is ur respnsibility as scientists, knwing the great prgress that is the fruit f freedm f thught, t declare the value f this freedm; t teach hw dubt is nt t be feared but t be welcmed and discussed; and t demand this freedm as ur duty t all cming generatins.
parallelism
Rhetrical device
Feyman uses this analgy t emphasize the curisity and determinatin that scientists use t uncver mysteries and answer questins.
Parallelism is the repetitin f similar grammatical frms. It helps make an idea r argument clear and easy t remember. It als shws that each repeated structure is f equal imprtance. Parallelism is a pwerful tl in public speaking and writing.
Feyman believes that f all science’s many values, the greatest must be the freedm t dubt. Hw d yu understand this?
This belief expresses a similar meaning t this unit's pening qute "The scientist is mtivated primarily by curisity and a desire fr truth." Only when scientists raise dubts can they pen up the pprtunity t explre the unknwn, which is what leads t scientific achievements. Feynman further emphasizes this value when he says, "Permit us t questin—t dubt—t nt be sure." He pints ut that scientists must always be allwed t questin and dubt things, because he knws it is the key t hw science is able t prgress.
