Fear not for the future, weep not for the past.

The line urges emotional steadiness: do not let anxiety about what has not happened (“the future”) or grief over what cannot be changed (“the past”) govern the present. Read as a Romantic-era counsel, it aligns with Shelleyan themes of liberation from oppressive mental states and the pursuit of a freer, more vital consciousness. The balanced parallelism (“Fear not… weep not…”) suggests a disciplined refusal of two common forms of suffering—anticipatory dread and retrospective sorrow—implying that agency and hope lie in present action and imagination rather than in rumination. It can also be taken as a secular, stoic-sounding maxim: equanimity comes from loosening attachment to time’s irreversibility.
