T 2.3.6.1

'TIS remarkable, that the imagination and affections have a close union together, and that nothing, which affects the former, can be entirely indifferent to the latter. Wherever our ideas of good or evil acquire a new vivacity, the passions become more violent; and keep pace with the imagination in all its variations. Whether this proceeds from the principle above-mention'd, that any attendant emotion is easily converted into the predominant, I shall not determine. 'Tis sufficient for my present purpose, that we have many instances to confirm this influence of the imagination upon the passions.
