Sonnet 9 by Shakespeare

Sonnet 9 is another of Shakespeare's procreation sonnets.

Synopsis
In it, he reasons that if the young man remains single so that he does not make a widow, he is wrong because if he dies the entire world will in effect be a widow, crying over the fact that he did not leave a child behind, or a copy of his beauty. To Shakespeare, a widow will always have the image of her children to console her after her loss.
 * Ah! if thou issueless shalt hap to die.
 * The world will wail thee, like a makeless wife;
 * The world will be thy widow and still weep
 * That thou no form of thee hast left behind,
 * When every private widow well may keep
 * By children's eyes her husband's shape in mind.

The sonnet ends with the scathing declaration that if the young man does not marry and have children, he is committing "murderous shame" upon himself.
 * No love toward others in that bosom sits
 * That on himself such murderous shame commits.
