Famous quotes containing the word events:
“It is the true office of history to represent the events themselves, together with the counsels, and to leave the observations and conclusions thereupon to the liberty and faculty of every mans judgement.”
—Francis Bacon (15611626)
“There is much to be said in favour of modern journalism. By giving us the opinions of the uneducated, it keeps us in touch with the ignorance of the community. By carefully chronicling the current events of contemporary life, it shows us of what very little importance such events really are. By invariably discussing the unnecessary, it makes us understand what things are requisite for culture, and what are not.”
—Oscar Wilde (18541900)
“Whatever events in progress shall disgust men with cities, and infuse into them the passion for country life, and country pleasures, will render a service to the whole face of this continent, and will further the most poetic of all the occupations of real life, the bringing out by art the native but hidden graces of the landscape.”
—Ralph Waldo Emerson (18031882)
