We are all born for love. It is the principle of existence, and its only end.

The line frames love not as a private sentiment but as a metaphysical principle: the force that explains why human beings exist and what their lives are ultimately for. By pairing “principle of existence” with “its only end,” the speaker collapses origin and purpose into a single ethical-spiritual claim—love is both the ground of being and the telos toward which life should be directed. The absolutist phrasing (“all,” “only”) gives it the character of a credo, implying that other aims—ambition, power, reputation—are secondary or even distortive if detached from love. Read in a Disraelian context, it also resonates with Romantic-era moral idealism, where personal feeling is elevated into a universal law.
