III. Of the Affects
P53: When the mind considers itself and its power of acting, it rejoices, and does so the more, the more distinctly it imagines itself and its power of acting.
Dem.: A man does not know himself except through affections of his body and their ideas (by IIP19 and P23). So when it happens that the mind can consider itself, it is thereby supposed to pass to a greater perfection, that is (by P11S), to be affected with joy, and with greater joy the more distinctly it can imagine its power of acting, q.e.d.
Cor.: This joy is more and more encouraged the more the man imagines himself to be praised by others. For the more he imagines himself to be praised by others, the greater the joy with which he imagines himself to affect others, a joy accompanied by the idea of himself (by P29S). And so (by P27) he himself is affected with a greater joy, accompanied by the idea of himself, q.e.d.
