Definition of "presumption"

I have here imputed the Continuance of the War to the mutual Indulgence between our General and Allies, wherein they both so well found their Accounts; to the Fears of the Mony-changers, left their Tables should be overthrown; to the Designs of the Whigs, who apprehended the Loss of their Credit and Employments in a Peace; and to those at home, who held their immoderate Engrossments of Power and Favour, by no other Tenure than their own Presumption upon the Necessity of Affairs.

The state, in the exercise of its general power to prescribe rules of evidence, may provide that proof of a particular fact, or of several facts taken collectively, shall be prima facie evidence of another fact when there is some rational connection between the fact proved and the ultimate fact presumed. The legislative presumption is invalid when it is entirely arbitrary, or creates an invidious discrimination, or operates to deprive a party of a reasonable opportunity to present the pertinent facts in his defense.
