Man depends upon cooperation, and has been provided by nature, somewhat inadequately, it is true, with the instinctive apparatus out of which the friendliness required for cooperation can spring.

Context

“All these are solitary philosophies in the sense that the good is supposed to be something realisable in each separate person, not only in a larger or smaller society of persons. All such views, to my mind, are false, and not only in ethical theory, but as expressions of the better part of our instincts. Man depends upon cooperation, and has been provided by nature, somewhat inadequately, it is true, with the instinctive apparatus out of which the friendliness required for cooperation can spring. Love is the first and commonest form of emotion leading to cooperation, and those who have experienced love with any intensity will not be content with a philosophy that supposes their highest good to be independent of that of the person loved.” source
