(Pertaining to the philosophy of altruism in romantic and all relationships ~What Dagney learns when asking Galt why he allowed his dearest friend Francisco to have first shot at the woman he himself loved)
This about sums it all up!

"Galt, giving up the woman he wanted for the sake of his friend, faking his greatest feeling out of existence and himself out of her life, no mater what the cost to him and to her, then dragging  the rest of his years through the waste of the unreached and the unfulfilled - she, turning for consolation to a second choice, faking a love she did not feel, being willing to fake, since her will to self-deceit was the essential required for Galt's self -sacrifice, then living out her years in hopeless longing, accepting, as relief for an unhealing wound, some moments of weary affection, plus the tenet that love is futile and happiness is not to be found on earth- Francisco, struggling in the elusive fog of a counterfeit reality, his life a fraud staged by the two who were dearest to him and most trusted, struggling to grasp what was missing from his happiness, struggling down the brittle scaffold of a lie over the abyss of the discovery that he was not the man she loved, but only a resented substitute, half-charity-patient, half-crutch, his perceptiveness becoming his danger and only his surrender to lethargic stupidity protecting the shoddy structure of his joy, struggling and giving up and settling into the dreary routine of conviction that fulfillment is impossible to man- the three of them, who had had all the gifts of existence spread out before them, ending up as embittered hulks who cry in despair that life is frustration - the frustration of not being able to make unreality real.”

 Galt makes things even more clear to Dagny, “Did it ever occur to you…that there is no conflict of interests among men, neither in business nor in trade nor in their most personal desires - if they omit the irrational from their view of the possible and destruction from their view of the practical?…The businessman who wishes to gain a market by throttling a superior competitor, the worker who wants a share of his employer’s wealth, the artist who envies a rival’s higher talent - they’re all wishing facts out of existence, and destruction is the only means of their wish. If they pursue it, they will not achieve a market, a fortune or an immortal fame - they will merely destroy production, employment and art.”
