It must be so — Plato, thou reasonest well!
Else whence this pleasing hope, this fond desire,
This longing after immortality?
Or whence this secret dread, and inward horror,
O falling into nought? Why shrinks the soul
Back on herself, and startles at destruction?
'Tis the divinity that stirs within us;
'Tis heaven itself, that points out an hereafter,
And intimates eternity to man.

Act V, scene i. - Cato, A Tragedy (1713)
