"No man is an island" || by John Donne (1624)

No man is an island,
Entire of itself.
Each is a piece of the continent,
A part of the main.
If a clod be washed away by the sea,
Europe is the less.
As well as if a promontory were.
As well as if a manor of thine own
Or of thine friend's were.
Each man's death diminishes me,
For I am involved in mankind.
Therefore, send not to know
For whom the bell tolls,
It tolls for thee.

John Donne, (1572 - 1631), was a leading English poet, scholar, soldier and secretary of the Metaphysical school and dean of St. Paul’s Cathedral, London. Donne is often considered the greatest love poet in the English language. He is also noted for his religious verse and treatises and for his sermons, which rank among the best of the 17th century. Donne was born of Roman Catholic parents when practice of that religion was illegal in England. His poetical works include sonnets, love poems, religious poems, Latin translations, epigrams, elegies, songs and satires. He is also known for his sermons.
