o the illuminations of Heaven,
consider yourselves as represented in this fable; for he that is once so
far overcome as to turn back his eyes towards the infernal caverns,
loses at the first sight all that influence which attracted him on
high:"

Vos haec fabula respicit,
Quicunque in superum diem
Mentem ducere quaeritis.
Nam qui Tartareum in specus
Victus lumina flexerit,
Quidquid praecipuum trahit,
Perdit, dum videt inferos.

It may be observed, in general, that the future is purchased by the
present. It is not possible to secure instant or permanent happiness but
by the forbearance of some immediate gratification. This is so evidently
true with regard to the whole of our existence, that all the precepts of
theology have no other tendency than to enforce a life of faith; a life
regulated not by our senses but our belief; a life in which pleasures
are to be refused for fear of invisible punishments, and calamities
sometimes to be sought, and always endured, in hope of rewards that
shall be obtained in another state.

Even if we take into our view only that particle of our duration which
is terminated by the grave, it will be found that we cannot enjoy one
part of life beyond the common limitations of pleasure, but by
anticipating some of the satisfaction which should exhilarate the
following years. The heat of youth may spread happiness into wild
luxuriance, but the radical vigour requisite to make it perennial is
exhausted, and all that can be hoped afterwards is languor and
sterility.

The reigning errour of mankind is, that we are not content with the
conditions on which the goods of life are granted. No man is insensible
of the value of knowledge, the advantages of health, or the convenience
of plenty, but every day shews us those on whom the conviction is
without effect.

Knowledge is praised and desired by multitudes whom her charms could
never rouse from the couch of sloth; whom the faintest invitation of
pleasure draws away from their studies; to whom any other method of
wearing out the day is more eligible than the use of books, and who are
more easily engaged by any conversation, than such as may rectify their
notions or enlarge their comprehension.

Every man that has felt pain, knows how little all other comforts can
gladden him to whom health is denied. Yet who is there does not
sometimes hazard it for the enjoyment of an hour? All assemblies of
jollity, all places of public enter
