Famous quotes containing the words external and/or links:
“My grief lies all within,
And these external manners of laments
Are merely shadows to the unseen grief
That swells with silence in the tortured soul.
There lies the substance.”
—William Shakespeare (1564–1616)
“Nor stony tower, nor walls of beaten brass,
Nor airless dungeon, nor strong links of iron,
Can be retentive to the strength of spirit.”
—William Shakespeare (1564–1616)
