Abstract
From the refusal of some parents to apply some vaccines to their
children, in this work we will show that to act properly it is not enough
with a good intellectual justification to validate a belief as accurate, it will
be necessary to take into account also the systematic actions in relation
to which we are constituted, as well as the feelings that accompany those
actions. We begin by exposing the notion of belief that Villoro presents
from authors such as Braithwaite and Bain. Next, we briefly explain the
topic of the justification of beliefs and then articulate it with some of the
controversies related to the application of vaccines. Later, we turned to
Hume to show the role of imagination in relation to pleasure and pain in
decision making. Finally, we present an outline of the discussion about
paternalism in the application of vaccines.
