Embryon Philosophers

Sir Thomas Browne, Hydriotaphia, Urn-Burial; or A brief Discourse of the Sepulchral Urns lately found in Norfolk (London: 1669) p. 22:

The particulars of future Beings must needs be dark unto ancient Theories, which Christian Philosophy yet determines but in a Cloud of Opinions.  A Dialogue between two Infants in the womb concerning the state of this world might handsomly illustrate our ignorance of the next, whereof methinks we yet discourse in Plato's Den, and are but Embryon Philosophers.

Shakespeare, Hamlet, (Act III, Scene i, 70-82):

For who would bear the whips and scorns of time,
The oppressor's wrong, the proud man's contumely,
The pangs of dispriz'd love, the law's delay,
The insolence of office, and the spurns
That patient merit of the unworthy takes,
When he himself might his quietus make
With a bare bodkin? who would fardels bear,
To grunt and sweat under a weary life,
But that the dread of something after death,
The undiscover'd country from whose bourn
No traveller returns, puzzles the will,
And makes us rather bear those ills we have
Than fly to others that we know not of?
