    It is the glorious prerogative of the empire of knowledge, that what it gains it never loses. On the contrary, it increases by the multiple of its own power: all its ends become means; all its attainments help to new conquests.

    Daniel Webster.

    Knowledge cannot be stolen from us. It cannot be bought or sold. We may be poor, and the sheriff may come and sell our furniture, or drive away our cow, or take our pet lamb, and leave us homeless and penniless; but he cannot lay the law’s hand upon the jewelry of our minds.

    Elihu Burritt.

  • Far must thy researches go
  • Wouldst thou learn the world to know;
  • Thou must tempt the dark abyss
  • Wouldst thou prove what Being is;
  • Naught but firmness gains the prize,
  • Naught but fullness makes us wise,
  • Buried deep truth e’er lies.
  • Schiller.

    Early knowledge is very valuable capital with which to set forth in life. It gives one an advantageous start. If the possession of knowledge has a given value at fifty, it has a much greater value at twenty-five; for there is the use of it for twenty-five of the most important years of your life; and it is worth more than a hundred per cent interest. Indeed, who can estimate the interest of knowledge? Its price is above rubies.


  • In reading authors, when you find
  • Bright passages, that strike your mind,
  • And which, perhaps, you may have reason
  • To think on, at another season,
  • Be not contented with the sight,
  • But take them down in black and white;
  • Such a respect is wisely shown,
  • As makes another’s sense one’s own.
  • Byron.

    There is nothing so charming as the knowledge of literature; of that branch of literature, I mean, which enables us to discover the infinity of things, the immensity of Nature, the heavens, the earth, and the seas; this is that branch which has taught us religion, moderation, magnanimity, and that has rescued the soul from obscurity; to make her see all things above and below, first and last, and between both; it is this that furnishes us wherewith to live well and happily, and guides us to pass our lives without displeasure and without offence.


    Pleasure is a shadow, wealth is vanity, and power a pageant; but knowledge is ecstatic in enjoyment, perennial in fame, unlimited in space, and infinite in duration. In the performance of its sacred offices, it fears no danger, spares no expense, looks in the volcano, dives into the ocean, perforates the earth, wings its flight into the skies, explores sea and land, contemplates the distant, examines the minute, comprehends the great, ascends to the sublime—no place too remote for its grasp, no height too exalted for its reach.

    De Witt Clinton.
