"It may not be impossible, but that our Faculties may be so construed, as always to deceive us in the things we judge most certain and assured"

This quote by Joseph Glanvill recommends that it is feasible for our detects and professors to be so misinterpreted that they can lead us to think something that is not true. He is recommending that even things we are most particular of can be tricking. This quote indicates that we need to be cautious and also not take every little thing at face value. We ought to be open to the possibility that our detects and faculties can be wrong which we should be willing to question our very own ideas. Glanvill is suggesting that we must be open to the concept that our detects and professors can be adjusted and that we need to be aware of this possibility. He is advising us to be cautious as well as to not take every little thing our team believe as absolute fact.
