An open secret is a concept or idea that is "officially" secret or restricted in knowledge, but is actually widely known; or refers to something which is widely known to be true, but which none of the people most intimately concerned are willing to categorically acknowledge in public.
Famous quotes containing the words open and/or secret:
“GOETHE, raised o’er joy and strife,
Drew the firm lines of Fate and Life,
And brought Olympian wisdom down
To court and mar, to gown and town,
Stooping, his finger wrote in clay
The open secret of to-day.”
—Ralph Waldo Emerson (1803–1882)
“How like a prodigal doth nature seem,
When thou, for all thy gold, so common art!
Thou teachest me to deem
More sacredly of every human heart,
Since each reflects in joy its scanty gleam
Of Heaven, and could some wondrous secret show,
Did we but pay the love we owe,
And with a child’s undoubting wisdom look
On all these living pages of God’s book.”
—James Russell Lowell (1819–1891)
