The sin against the virtue of hope by apparent excess, the opposite extreme to the sin by real defect, which is despair. In presumption the excess is apparent rather than real, because it is impossible to hope too much, if by hope is meant aspiring to the good that God has promised and relying on the means that He has made available. Instead of hoping too much, one who presumes substitutes for the Christian virtue a distorted counterfeit that looks to a good or trusts in means other than those guaranteed by God's promise.
Like despair, presumption may be based upon a corruption of faith, in which case one presumes because he thinks perversely about the object or motive of hope. This is known as heretical presumption, which is a sin primarily and directly contrary to faith, rather than to hope. Such would be presumption based on the belief that God will not punish sin. In distinction to this, simple presumption, which is directly opposed to hope, supposes no false belief, but arises from a failure to make practical application to oneself of the truths known by faith.
There is a kind of presumption that is opposed to the moral virtue of magnanimity rather than to hope, as when one aspires to something humanly possible, but beyond the limits that a reasonable estimate of one's capacities should impose.
Theologians distinguish two kinds of the simple presumption opposed properly to hope. One kind is directly opposed to hope and essentially corruptive of the virtue (praesumptio contra spem ); it either rejects hope's proper motive and looks for the attainment of eternal life by one's own unaided efforts, or it expects salvation by a gift of God that would be incompatible with the divine perfections (as when one expects salvation without repentance for sin). The other kind of presumption consists in trusting beyond the limits of hope (praeter spem ), but in a way not essentially corruptive of the virtue, as when one looks rashly to God for what God could, but has not promised, to give; for example, extraordinary graces or an extended opportunity for repentance at the end of life.
Presumption directly contrary to hope is always a grave sin unless its malice is lessened by an imperfection of awareness or consent. As a sin directly opposed to a theological virtue, it is more serious, other things being equal, than a sin against a moral virtue. Because it involves a repudiation of God's plan for one's salvation, it is listed by some as a sin against the Holy Spirit. Nevertheless, it is not as grave as the sin of despair, because its affront to divine justice dishonors God less than that of despair to divine mercy, mercy being more characteristic of God than justice (St. Thomas Aquinas, Summa theologiae 2a2ae, 21.3).
Presumption of the kind called praeter spem may be seriously or venially sinful. Provided there is no serious want of submission to divine providence and no contempt of the ordinary means of salvation, it is not grievously sinful to hope for extraordinary graces or favors, although such hope is likely to be inspired by an inordinate vanity or egoism.

[p. k. meagher]
pre·sump·tion / priˈzəmpshən/ • n. 1. an act or instance of taking something to be true or adopting a particular attitude toward something, esp. at the start of a chain of argument or action: the presumption of guilt has changed to a presumption of innocence. ∎ an idea that is taken to be true, and often used as the basis for other ideas, although it is not known for certain: underlying presumptions about human nature. ∎ chiefly Law an attitude adopted in law or as a matter of policy toward an action or proposal in the absence of acceptable reasons to the contrary: the planning policy shows a general presumption in favor of development.2. behavior perceived as arrogant, disrespectful, and transgressing the limits of what is permitted or appropriate: he lifted her off the ground and she was enraged at his presumption.
A conclusion made as to the existence or nonexistence of a fact that must be drawn from other evidence that is admitted and proven to be true. Arule of law.
If certain facts are established, a judge or jury must assume another fact that the law recognizes as a logical conclusion from the proof that has been introduced. A presumption differs from an inference, which is a conclusion that a judge or jury may draw from the proof of certain facts if such facts would lead a reasonable person of average intelligence to reach the same conclusion.
A conclusive presumption is one in which the proof of certain facts makes the existence of the assumed fact beyond dispute. The presumption cannot be rebutted or contradicted by evidence to the contrary. For example, a child younger than seven is presumed to be incapable of committing a felony. There are very few conclusive presumptions because they are considered to be a substantive rule of law, as opposed to a rule of evidence.
A rebuttable presumption is one that can be disproved by evidence to the contrary. The federal rules of evidence and most state rules are concerned only with rebuttable presumptions, not conclusive presumptions.
