      Benjamin Franklin, Walter Isaacson tells us at the beginning of his long (but never boring)new

biography(传记), "is the founding father who winks at us."By that, Isaacson explains, he means

Franklin is the most human-and most modern-of the men who shaped the American republic.We

admire Washington, Jefferson and Adams, but they remain creatures of the 18th century.The man

we encounter in"Benjamin Franklin"-funny, pragmatic and selfaware-seems like one of us, or at least

someone we'd like to be.

     Unlike Washington's cherry tree, Franklin's kite was real.His experiments with electricity made

him one of the great scientists of his day.He was a middleclass businessman whose success as a printer

and a journalist allowed him to retire at 42-and he devoted the rest of his life to his country.He was

diplomat who persuaded the French to back the American Revolution and the author of the first great

American autobiography.He was an excellent swimmer.There was almost nothing he couldn't do well,

except write poetry.But what truly distinguished Franklin was his talent of being great and human at the

same time.He owned slaves as a younger man, but in his last years became an abolitionist(废奴主义者). When he fathered an illegitimate(私生的) son, he acknowledged his fatherhood and took the

responsibility of raising the boy.

     He seems strange today in the joy he took in compiling and creating all  those selfimprovement

maxims he published in Poor Richard's Almanac(年鉴)- "early to bed, early to rise"and so on.

Generations of lazy boys could have been happier without that.But he was no hypocrite.Isaacson tells

us Franklin practiced what he preached, and often laughed at himself while he did so.

    By a happy accident, this is the second excellent biography of Franklin to appear in two years, after

Edmund S. Morgan's inspiring"Benjamin Franklin."
