What's the difference between presume and proof?

Presume


Definition:

  • (v. t.) To assume or take beforehand; esp., to do or undertake without leave or authority previously obtained.
  • (v. t.) To take or suppose to be true, or entitled to belief, without examination or proof, or on the strength of probability; to take for granted; to infer; to suppose.
  • (v. i.) To suppose or assume something to be, or to be true, on grounds deemed valid, though not amounting to proof; to believe by anticipation; to infer; as, we may presume too far.
  • (v. i.) To venture, go, or act, by an assumption of leave or authority not granted; to go beyond what is warranted by the circumstances of the case; to venture beyond license; to take liberties; -- often with on or upon before the ground of confidence.

  • (20) In addition, we have shown that long-lived, presumably non-senescent, strains do not arise by suppressor mutation, but lose senescence plasmid DNA by another mechanism.
