verb
presume
prih-ZOOM/prɪˈzuːm/
To accept something as true without definite proof.
The person presumes it is raining after noticing the umbrella beside the door.

Etymology
To “take beforehand” became to anticipate or assume. In this sense, what is taken in advance is something’s truth: it is accepted on probable evidence rather than certain proof.
In context
The French lodges had all emanated from the great confederation under the Duc de Chartres, and even if we had no other proof, we might presume that they would cultivate the same principles that characterised that sect.
