“Revolution requires extensive and widespread destruction, a fecund and renovating destruction, since in this way and only this way are new worlds born”

Allocution to Midwives on the Nature of Their Profession, October 29, 1951. http://www.ewtn.com/library/PAPALDOC/P511029.HTM http://www.papalencyclicals.net/Pius12/P12midwives.htm
Context: Besides, every human being, even the child in the womb, has the right to life directly from God and not from his parents, not from any society or human authority. Therefore, there is no man, no human authority, no science, no "indication" at all—whether it be medical, eugenic, social, economic, or moral—that may offer or give a valid judicial title for a direct deliberate disposal of an innocent human life, that is, a disposal which aims at its destruction, whether as an end in itself or as a means to achieve the end, perhaps in no way at all illicit. Thus, for example, to save the life of the mother is a very noble act; but the direct killing of the child as a means to such an end is illicit. The direct destruction of so-called "useless lives," already born or still in the womb, practiced extensively a few years ago, can in no wise be justified. Therefore, when this practice was initiated, the Church expressly declared that it was against the natural law and the divine positive law, and consequently that it was unlawful to kill, even by order of the public authorities, those who were innocent, even if on account of some physical or mental defect, they were useless to the State and a burden upon it. The life of an innocent person is sacrosanct, and any direct attempt or aggression against it is a violation of one of the fundamental laws without which secure human society is impossible. We have no need to teach you in detail the meaning and the gravity, in your profession, of this fundamental law. But never forget this: there rises above every human law and above every "indication" the faultless law of God.

Context: True ideology has vanished, replaced by fear and fantasy. The right wing wants corporate control and a return to a past that never existed. The left wing wants government control and a future that will never exist. Both groups lose sight of the essential questions: how can the individual speak and think and create freely? New ideas are the only evolutionary force that will save us from destruction.

Context: There are, and always have been, destructive pseudo-scientific notions linked to race and religion; these are the most widespread and damaging. Hopefully, educated people can succeed in shedding light into these areas of prejudice and ignorance, for as Voltaire once said: "Men will commit atrocities as long as they believe absurdities."

Speech to Conservative Central Council ("The Historic Choice") (20 March 1976) http://www.margaretthatcher.org/document/102990
Leader of the Opposition
Context: Every step this Socialist Government takes to seize more power over our daily lives diminishes those lives and the freedom which is their essence and their strength. One of our principal and continuing priorities when we are returned to office will be to restore the freedoms which the Socialists have usurped. Let them learn that it is not a function of the State to possess as much as possible. It is not a function of the State to grab as much as it can get away with. It is not a function of the State to act as ring-master, to crack the whip, dictate the load which all of us must carry or say how high we may climb. It is not a function of the State to ensure that no-one climbs higher than anyone else. All that is the philosophy of Socialism. We reject it utterly for, however well-intended, it leads in one direction only: to the erosion and finally the destruction of the democratic way of life.
