Bertrand Russell said this quote

There is another more psychological obstacle to the full development of love in the modern world, and that is the fear that many people feel of not preserving their individuality in tact. This is a foolish and rather modern terror. Individuality is not an end in itself; it is something that must enter into fructifying contact with the world, and in so doing must lose its separateness. An individuality which is kept in a glass case withers, whereas on e that is freely expended in human contacts becomes enriched.
