which, in consequence, he attributes this quality? What is it that
represents the word _intelligence_, if he does not connect it with a
certain mode of being and of acting? Does the word _order_ signify any
thing, if he does not relate it to a series of actions, to a chain of
motion, by which he is affected in a certain manner? Is not the word
_virtue_ void of sense, if he does not apply it to those dispositions of

_pleasure_ offer to his mind in the moment when his organs neither
suffer nor enjoy, if it be not the modes in which he has been affected,
of which his brain conserves the remembrance, of those impressions,
which experience has shewn him to be either useful or prejudicial? But
when he bears the words spirituality, immateriality, incorporeality, &c.
pronounced, neither his senses nor his memory afford him any assistance;
they do not furnish him with any means by which he can form an idea of
their qualities, or of the objects to which he ought to apply them; in
that which is not matter he can only see vacuum and emptiness, which as
long as he remains what he is, cannot, to his mind, be susceptible of
any one quality.

All the errors, all the disputes of men, have their foundation in this,

which they have been instructed from their infancy, with which habit has
familiarized them, which authority has obliged them to conserve.
Languages are filled with abstract words, to which are attached confused
and vague ideas; of which, when they come to be examined, no model can
be found in Nature; no object to which they can be related. When man
