63. Jesus tells the story of a man assaulted by thieves and lying injured on the wayside. Several persons passed him by, but failed to stop. These were people holding important social positions, yet lacking in real concern for the common good. They would not waste a couple of minutes caring for the injured man, or even in calling for help. Only one person stopped, approached the man and cared for him personally, even spending his own money to provide for his needs. He also gave him something that in our frenetic world we cling to tightly: he gave him his time. Certainly, he had his own plans for that day, his own needs, commitments and desires. Yet he was able to put all that aside when confronted with someone in need. Without even knowing the injured man, he saw him as deserving of his time and attention.

89. Nor can I reduce my life to relationships with a small group, even my own family; I cannot know myself apart from a broader network of relationships, including those that have preceded me and shaped my entire life. My relationship with those whom I respect has to take account of the fact that they do not live only for me, nor do I live only for them. Our relationships, if healthy and authentic, open us to others who expand and enrich us. Nowadays, our noblest social instincts can easily be thwarted by self-centred chats that give the impression of being deep relationships. On the contrary, authentic and mature love and true friendship can only take root in hearts open to growth through relationships with others. As couples or friends, we find that our hearts expand as we step out of ourselves and embrace others. Closed groups and self-absorbed couples that define themselves in opposition to others tend to be expressions of selfishness and mere self-preservation.
221. Such a covenant also demands the realization that some things may have to be renounced for the common good. No one can possess the whole truth or satisfy his or her every desire, since that pretension would lead to nullifying others by denying their rights. A false notion of tolerance has to give way to a dialogic realism on the part of men and women who remain faithful to their own principles while recognizing that others also have the right to do likewise. This is the genuine acknowledgment of the other that is made possible by love alone. We have to stand in the place of others, if we are to discover what is genuine, or at least understandable, in their motivations and concerns.
286. In these pages of reflection on universal fraternity, I felt inspired particularly by Saint Francis of Assisi, but also by others of our brothers and sisters who are not Catholics: Martin Luther King, Desmond Tutu, Mahatma Gandhi and many more. Yet I would like to conclude by mentioning another person of deep faith who, drawing upon his intense experience of God, made a journey of transformation towards feeling a brother to all. I am speaking of Blessed Charles de Foucauld.
It was not until the beginning of 1935 that a polymer called "polymer 6-6" was finally produced. Carothers' coworker, Washington University alumnus Julian W. Hill had used a cold drawing method to produce a polyester in 1930.[21] This cold drawing method was later used by Carothers in 1935 to fully develop nylon.[22] The first example of nylon (nylon 6.6) was produced on February 28, 1935, at DuPont's research facility at the DuPont Experimental Station.[13] It had all the desired properties of elasticity and strength.However, it also required a complex manufacturing process that would become the basis of industrial production in the future. DuPont obtained a patent for the polymer in September 1938,[23] and quickly achieved a monopoly of the fiber.[11] Carothers died 16 months before the announcement of nylon, therefore he was never able to see his success.[9]
Although pure nylon has many flaws and is now rarely used, its derivatives have greatly influenced and contributed to society. From scientific discoveries relating to the production of plastics and polymerization, to economic impact during the depression and the changing of women's fashion, nylon was a revolutionary product.[18] The Lunar Flag Assembly, the first flag planted on the moon in a symbolic gesture of celebration, was made of nylon. The flag itself cost $5.50, but had to have a specially designed flagpole with a horizontal bar so that it would appear to "fly".[48][49]One historian describes nylon as "an object of desire", comparing the invention to Coca-Cola in the eyes of 20th century consumers.[8]
Wallace Carothers at DuPont patented nylon 66 using amides.[23][54][55] In the case of nylons that involve reaction of a diamine and a dicarboxylic acid, it is difficult to get the proportions exactly correct, and deviations can lead to chain termination at molecular weights less than a desirable 10,000 daltons (u). To overcome this problem, a crystalline, solid "nylon salt" can be formed at room temperature, using an exact 1:1 ratio of the acid and the base to neutralize each other. The salt is crystallized to purify it and obtain the desired precise stoichiometry. Heated to 285 C (545 F), the salt reacts to form nylon polymer with the production of water.
