William Shakespeare (1564–1616) was an English playwright and poet whose comedies, tragedies, and histories remain among the most widely read works in world literature. The advice “Love all, trust a few, do wrong to none” is from his play *All’s Well That Ends Well*. In the first act, the Countess offers it to her son, Bertram, as guidance for how to treat other people: be generous in affection, cautious about trust, and careful not to cause harm.
The saying about kindness being “the language which the deaf can hear and the blind can see” is a separate line, widely attributed to Mark Twain, but its source has not been reliably established. So the full wording here combines two sayings rather than forming a single Shakespeare quotation. Together, they make a memorable point: good conduct depends both on discernment and compassion. Trust need not be given indiscriminately, but kindness can still be offered broadly—and its meaning often comes through in actions, not words. That idea resonates because it joins practical self-protection with a humane obligation to others.
