Origin of the phrase 'Ignorance is bliss'
The earliest known mention of the phrase can be found in English poet, Thomas Gray'sOde on a Distant Prospect of Eton College. The ode was composed by Gray in 1742, which sees him reminiscing about his schooldays, which were spent in joyful abandon.

The phrase 'ignorance is bliss' appears at the very end of the ode, signifying that sometimes, it is better to seek solace in our ignorance, rather than invite misery, courtesy of our awareness.
To each his sufferings: all are men,
Condemned alike to groan;
The tender for another's pain,
The unfeeling for his own.
Yet ah! why should they know their fate?
Since sorrow never comes too late,
And happiness too swiftly flies.
Thought would destroy their paradise.
No more; where ignorance is bliss,
'Tis folly to be wise
.
Although the phrase 'ignorance is bliss' worded as such was coined by Thomas Gray, the idea itself dates back at least to the times of Sophocles, who alluded to the concept circa 450 - 430 BCE in Ajax.

... of woes thou knowest naught, for ignorance is life's extremest bliss ...
William Davenant wrote about it in his play, The Just Italian (1629).

Since Knowledge is but sorrow's Spy,
It is not safe to know.
Poet Matthew Prior (1664 - 1721) wrote,If We see right, We see our Woes:
Then what avails it to have Eyes?
From Ignorance our Comfort flows:
The only wretched are the Wise.
Use it right
