Page 624 - And God said unto him, Because thou hast asked this thing, and hast not asked for thyself long life; neither hast asked riches for thyself, nor hast asked the life of thine enemies ; but hast asked for thyself understanding to discern judgment; behold, I have done according to thy word: lo, I have given thee a wise and an understanding heart; so that there was none like thee before thee, neither after thee shall any arise like unto thee.
Page 624 - Give therefore thy servant an understanding heart to judge thy people, that I may discern between good and bad: for who is able to judge this thy so great a people ? And the speech pleased the Lord, that Solomon had asked this thing.
Page 624 - Ask what I shall give thee. And Solomon said, Thou hast shewed unto thy servant David my father great mercy, according as he walked before thee in truth, and in righteousness, and in uprightness of heart with thee; and thou hast kept for him this great kindness, that thou hast given him a son to sit on his throne, as it is this day.
Page 601 - But what shall we think of a community that gives the charter of a university to an institution with a total of $20,000 endowment, two so-called professors, and eighteen students ! or another with three professors, twelve students, and a total of $27,000 endowment, mostly invested in buildings ! And yet there are very many similar institutions ; there being sixteen with three professors or less, and very many indeed with only four or five. Such facts as these could only exist in a democratic country,...
Page 593 - Our glance must not be backward; for however beautiful leaves and blossoms are, and however marvelous their rapid increase, they are but leaves and blossoms after all. Rather should we look forward to discover what will be the outcome of all this, and what the chance of harvest. For if we do this in time, we may discover the worm which threatens the ripe fruit, or the barren spot where the harvest is withering for want of water. I am required to address the so-called physical section of this association....
Page 670 - ... needle, with a force varying inversely as the square of the distance ; but that the action of the particles of the fluid in the wire is neither to attract nor to repel either poles of a magnetic particle, but a tangential force which has a tendency to place the poles of either...
Page 624 - ... behold, I have done according to thy words: lo, I have given thee a wise and an understanding heart; so that there was none like thee before thee, neither after thee shall any arise like unto thee. And I have also given thee that which thou hast not asked, both riches and honour: so that there shall not be any among the kings like unto thee all thy days.
Page 599 - ... prominently the aim that there can be no mistake. If our aim in life is wealth, let us honestly engage in commercial pursuits, and compete with others for its possession ; but if we choose a life which we consider higher, let us live up to it, taking wealth or poverty as it may chance to come to us, but letting neither turn us aside from our pursuit. The work of teaching may absorb the energies of many ; and, indeed, this is the excuse given by most for not doing any scientific work. But there...
Page 618 - I value in a scientific mind most of all that love of truth, that care in its pursuit and that humility of mind which makes the possibility of error always present more than any other quality. This is the mind which has built up modern science to its present perfection, which has laid one stone upon the other with such care that it to-day offers to the world the most complete monument to human reason.
Page 600 - I have not included the value of grounds and buildings, for this is of little importance, either to the present or future standing of the institution. As good work can be done in a hovel as in a palace. I have taken the productive funds of the institution as the basis of estimate. I find: 234 have below $500,000 8 " between $500,000 and $1,000,000 8 " over $1,000,000 There is no fact more firmly established, all over the world, than that the higher education can never be made to pay for itself.
