eral
course of their conduct, to dismiss business, and exclude pleasure, and
to devote their days and nights to a particular attention. But all
common degrees of excellence are attainable at a lower price; he that
should steadily and resolutely assign to any science or language those
interstitial vacancies which intervene in the most crowded variety of
diversion or employment, would find every day new irradiations of
knowledge, and discover how much more is to be hoped from frequency and
perseverance, than from violent efforts and sudden desires; efforts
which are soon remitted when they encounter difficulty, and desires,
which, if they are indulged too often, will shake off the authority of
reason, and range capriciously from one object to another.

The disposition to defer every important design to a time of leisure,
and a state of settled uniformity, proceeds generally from a false
estimate of the human powers. If we except those gigantic and stupendous
intelligences who are said to grasp a system by intuition, and bound
forward from one series of conclusions to another, without regular steps
through intermediate propositions, the most successful students make
their advances in knowledge by short flights, between each of which the
mind may lie at rest. For every single act of progression a short time
is sufficient; and it is only necessary, that whenever that time is
afforded, it be well employed.

Few minds will be long confined to severe and laborious meditation; and
when a successful attack on knowledge has been made, the student
recreates himself with the contemplation of his conquest, and forbears
another incursion, till the new-acquired truth has become familiar, and
his curiosity calls upon him for fresh gratifications. Whether the time
of intermission is spent in company, or in solitude, in necessary
business, or in voluntary levities, the understanding is equally
abstracted from the object of inquiry; but, perhaps, if it be detained
by occupations less pleasing, it returns again to study with greater
alacrity than when it is glutted with ideal pleasures, and surfeited
with intemperance of application. He that will not suffer himself to be
discouraged by fancied impossibilities, may sometimes find his abilities
invigorated by the necessity of exerting them in short intervals, as the
force of a current is increased by the contraction of its channel.

From some cause like this, it has probably proceeded, that
