  • Quotations:

    On exactitude:

     Le moyen infaillible de rajeunir une citation
     est de la faire exacte.
    
     Emile Faguet (1847-1916)
    

    On advocacy:

     Bring vor, was wahr ist;
     schreib so, dass es klar ist.
     Und verficht's bis
     es mit dir gar ist!
    
     Ludwig Boltzmann (1844-1906)
    

    On fortitude:

     I believe that despite the enormous odds which exist,
     unflinching, unswerving, fierce intellectual determination,
     as citizens, to define the real truth of our lives and our
     societies is a crucial obligation which devolves upon us all.
     It is in fact mandatory.
    
     Harold Pinter (1930-2008)
    

    On purpose:

     Live modestly and do serious things.
    
     Dorothy Mary Crowfoot Hodgkin (1910-1994)
    

    On perseverance:

     I do not enter into that notion of varying ones 
     plans to keep the Publick in good humour...
     I imagine myself driving a nail. 
     I have driven it some way -- 
     by persevering with this nail I may drive it home.
    
     John Constable (1776-1837)
    

    On provisionality:

     Now the best principles, excepting divine, and mathematical,
     are but hypotheses, within the circle of which we may indeed
     conclude many things, with security from error. But yet the
     greatest certainty, advanced from supposal, is still but
     hypothetical. So that we may affirm, things are thus and
     thus, according to the principles we have espoused. But we
     strangely forget ourselves, when we plead a necessity of
     their being so in nature, and an impossibility of their
     being otherwise.
    
     Joseph Glanvill (1636-1680)
    

    On skepticism:

     I keep six honest serving-men
     (They taught me all I knew);
     Their names are What and Why and When
     And How and Where and Who.
    
     Rudyard Kipling (1865-1936)
    

    On equivocation:

     Three reasons have been given for attacking Iraq.
     One is to get rid of weapons of mass destruction;
     the second is to destroy the link with al-Qaida;
     the third is to get rid of a bad regime.
     It depends which day of the week you talk to them,
     or perhaps to whom you talk, which one is emphasised.
     My personal opinion is that none of these three matter really.
     The decision to get rid of the regime was made a long time ago;
     it is nothing to do with al-Qaida.
     It is part of a policy of pursuing US dominance.
    
     Joseph Rotblat (1908-2005)
    

    On character:

     Nearly all men can stand adversity,
     but if you want to test a man's character,
     give him power.
    
     Abraham Lincoln (1809-1865)
    

    On responsibility:

     The disappearance of a sense of responsibility is the
     most far-reaching consequence of submission to authority.
     
     Stanley Milgram (1933-1984)
    

    On patriotism:

     Man is the only Patriot. He sets himself apart in his own country,
     under his own flag, and sneers at the other nations,
     and keeps multitudinous uniformed assassins on hand at heavy expense
     to grab slices of other people's countries,
     and to keep them from grabbing slices of his.
     And in the intervals between campaigns he washes the blood off his hands
     and works for "the universal brotherhood of man" -- with his mouth.
    
     Mark Twain (1835-1910)
    

    On political rights:

     Political rights do not originate in parliaments; they are, rather,
     forced on parliaments from without. And even their enactment into law
     has for a long time been no guarantee of their security...
     Political rights do not exist because they have been legally set down
     on a piece of paper, but only when they have become the ingrown habit
     of a people...
     We compel respect from others when we know how to defend our
     dignity as human beings. This is not only true in private life,
     it has always been the same in political life as well.
    
     Rudolf Rocker (1873-1958)
    

    On monarchy:

     Probably in most cases the greatest wisdom of a constitutional 
     king would show itself in well considered inaction. 
    
     Walter Bagehot (1826-1877) 
    

    On the wealth of nations:

     All for ourselves, and nothing for other people, seems, in every age
     of the world, to have been the vile maxim of the masters of mankind.
    
     Adam Smith (1723-1790)
    

    On justice:

     If you are neutral in situations of injustice,
     you have chosen the side of the oppressor.
    
     Desmond Mpilo Tutu (b. 1931)
    

    On democracy:

     I have hinted that what people are afraid of in democracy is less
     the thing itself than what they conceive to be its necessary
     adjuncts and consequences. It is supposed to reduce all mankind
     to a dead level of mediocrity in character and culture, to
     vulgarize men's conceptions of life, and therefore their code of
     morals, manners, and conduct - to endanger the rights of property
     and possession. But I believe that the real gravamen of the
     charges lies in the habit it has of making itself generally
     disagreeable by asking the Powers that Be at the most
     inconvenient moment whether they are the powers that ought to be.
     If the powers that be are in a condition to give a satisfactory
     answer to this inevitable question, they need feel in no way
     discomfited by it.
    
     James Russell Lowell (1819-1891)
    

    On independence:

     If you always do what interests you,
     at least one person is pleased.
    
     Katherine Hepburn (1907-2003)
    

    On humanity:

     What do we live for if not to make the
     world less difficult to each other?
    
     Mary Ann Evans (1819-1880)
    

    On intellectual property:

     He who receives an idea from me, receives instruction
     himself without lessening mine; as he who lights his
     taper at mine, receives light without darkening me.
    
     Thomas Jefferson (1743-1826)
    

    On mathematics:

     The science of numbers is at
     the root of all the sciences,
     the foundation of wisdom,
     the source of knowledge
     and the pillar of meaning.
