they keep it in Life, and Strength, and Vigour; nor is it possible for
the Mind to perform its Offices without their Assistance: These
Motions are given us with our Being, they are little Spirits that are
born and dye with us; to some they are mild, easie, and gentle, to
others wayward and unruly, yet never too strong for the Reins of
Reason and the Guidance of Judgment.

We may generally observe a pretty nice Proportion between the Strength
of Reason and Passion; the greatest Genius's have commonly the
strongest Affections, as on the other hand, the weaker Understandings
have generally the weaker Passions; and 'tis fit the Fury of the
Coursers should not be too great for the Strength of the Charioteer.
Young Men whose Passions are not a little unruly, give small Hopes of
their ever being considerable; the Fire of Youth will of course abate,
and is a Fault, if it be a Fault, that mends every Day; but surely
unless a Man has Fire in Youth, he can hardly have Warmth in Old Age.
We must therefore be very cautious, lest while we think to regulate
the Passions, we should quite extinguish them, which is putting out
the Light of the Soul: for to be without Passion, or to be hurried
away with it, makes a Man equally blind. The extraordinary Severity
used in most of our Schools has this fatal Effect, it breaks the
Spring of the Mind, and most certainly destroys more good Genius's
than it can possibly improve. And surely 'tis a mighty Mistake that
the Passions should be so intirely subdued; for little Irregularities
are sometimes not only to be borne with, but to be cultivated too,
since they are frequently attended with the greatest Perfections. All
great Genius's have Faults mixed with their Virtues, and resemble the
flaming Bush which has Thorns amongst Lights.

Since, therefore the Passions are the Principles of human Actions, we
must endeavour to manage them so as to retain their Vigour, yet keep
them under strict Command; we must govern them rather like free
Subjects than Slaves, lest while we intend to make them obedient, they
become abject, and unfit for those great Purposes to which they were
designed. For my Part I must confess, I could never have any Regard to
that Sect of Philosophers, who so much insisted upon an absolute
Indifference and Vacancy from all Passion; for it seems to me a Thing
very inconsistent for a Man to divest himself of Humanity
