==== Human connection ====
According to Havelock Ellis, a fulfilling marriage is one that possesses both the "art of love" and "science of procreation".<ref>{{Cite book |last=Ellis |first=Havelock |title=Studies in the Psychology of Sex, Volume VI, Sex in Relation to Society |publisher=Philadelphia : F.A.

{{Blockquote|text=Without the factor of mutual love the proper conditions for procreation cannot exist; without the factor of procreation the sexual union, however beautiful and sacred a relationship it may in itself be, remains, in essence, a private relationship, incomplete as a marriage and without public significance.|author=Havelock Ellis (1921)|title=Studies in the Psychology of Sex, Volume VI, Sex in Relation to Society, p. 508}}
Ellis states that a genuine and mutual connection to the other is needed for proper sexual intercourse. However, if the marriage lacks procreation, the relationship may lack understanding between partners and become superficial. Love is believed to have a nurturing aspect and is not wholly determined by instinct. "They believe, no art of love to be either learnt or taught; it comes by nature. Nothing could be further from the truth, most of all as regards civilized man.<ref>{{Cite book |last=Ellis |first=Havelock |title=Studies in the Psychology of Sex, Volume VI, Sex in Relation to Society |publisher=Philadelphia : F.A. Davis Co. |year=1921 |pages=510 |language=English}}</ref>" The role of love has a direct impact on proper sexual intercourse, which shares many similarities to the principles of marriage and thus a fulfilling happiness beyond the act of procreation.
{{Blockquote|text=The art of love certainly includes such primary facts of sexual hygiene, but it involves also the whole erotic discipline of marriage, and that is why its significance is so great, for the welfare and happiness of the individual, for the stability of sexual unions, and indirectly for the race, since the art of love is ultimately the art of attaining the right conditions for procreation.|author=Havelock Ellis (1921)|title=Studies in the Psychology of Sex, Volume VI, Sex in Relation to Society, p. 511}}
