“…for other women, it is totally unacceptable in 2017 to say that women should have to answer that question in the workplace. That is unacceptable in 2017. It is the woman's decision about when they choose to have children.”

Jacinda Ardern (1980) Prime Minister of New Zealand

“The discounting presumably is to be done for each period of time at that rate of interest which represents the alternative cost of employing capital in the occupation in question; that is, at the rate which the entrepreneur could obtain in other investments”

Kenneth E. Boulding (1910–1993) British-American economist

“We…would nevertheless make it clear that entirely independent political structures are impossible here [in the Baltic]…They cannot lead an isolated existence between the colossi of West and East. We hope that they will seek and find this support with us. The German occupation will have to continue for a long time, lest the anarchy we have just been combating should arise again. We shall have to safeguard the position of the Germans, a position consistent with their economic and cultural achievements…Herr Scheiddemann, said that we have made ourselves new enemies in the world through our push in the East…Had we continued the negotiations, we should still be sitting with Herr Trotski in Brest Litovsk. As it is, the advance has brought us peace in a few days and I think we should recognise this and not delude ourselves, particularly as regards the East, that if by resolutions made here in the Reichstag or through our Government's acceptance of the entirely welcome initiative of His Holiness the Pope, we had agreed to a peace without indemnities and annexations, we should have had peace in the East. In view of our situation as a whole, I should regard a fresh peace offer as an evil. My chief objection is against the detachment of the Belgian question from the whole complex of the question of peace. It is precisely if Belgium is not to be annexed that Belgium is the best dead pledge we hold, notably as regards England. The restoration of Belgium before we conclude peace with England seems to me an utter political and diplomatic impossibility…There is a great difference between the first set of terms at Brest-Litovsk and the ultimatum that we have now presented, and the blame for this change rests with those who refused to come to an agreement with Germany and who, consequently, must now feel her power. We are just as free to choose between understanding and the exploitation of victory in the case of the West, and I hope that these eight or fourteen days that have elapsed between the first set of peace terms in Brest-Litovsk and the second set, may also have an educational effect in that direction.”

Gustav Stresemann (1878–1929) German politician, statesman, and Nobel Peace Prize laureate

“There were a significant number of questions I had asked myself and, as you know, when you really ask yourself the questions, you give better answers than if we merely read the conventional answers.”

Albert Messiah (1921–2013) French physicist

Il y avait un nombre important de questions que je m'étais posées et, comme vous le savez, lorsqu'on se pose vraiment les questions, on donne de meilleures réponses que si l'on se contente de lire les réponses convenues.

“Today, for the first time since the existence of societies it is a question of organizing a totally new system; of replacing the celestial with the terrestrial, the vague by the positive, and the poetic by the real.”

[A]ujourd'hui … [i]l est question, pour la première fois depuis l'existence des sociétés, d'organiser un système tout-à-fait nouveau, de remplacer le céleste par le terrestre, le vague par le positif, le poétique par le réel.

“The only question with wealth is, what do you do with it?”

John D. Rockefeller (1839–1937) American business magnate and philanthropist

Though attributed to John D. Rockefeller, Sr. in I Want to Make Money in the Stock Market : Learn to Begin Investing Without Losing Your Life Savings (2006) by Chris M. Hart, p. 169; this is clearly a statement of his son, John D. Rockefeller, Jr., as quoted in John D. Rockefeller, Jr: A Portrait (1956) by Raymond Blaine Fosdick, p. 189: The only question with wealth is what to do with it. It can be used for evil purposes or it can be an instrumentality for constructive social living.

“Modern positivism…expresses criticism against the naïve use of certain terms… by the general postulate that the question whether a given sentence has any meaning… should always be thoroughly and critically examined. This… is derived from mathematical logic. The procedure of natural science is pictured as an attachment of symbols to the phenomena. The symbols can, as in mathematics, be combined according to certain rules… However, a combination of symbols that does not comply with the rules is not wrong but conveys no meaning.
The obvious difficulty in this argument is the lack of any general criterion as to when a sentence should be considered meaningless. A definite decision is possible only when the sentence belongs to a closed system of concepts and axioms, which in the development of natural science will be rather the exception than the rule. In some case the conjecture that a certain sentence is meaningless has historically led to important progress… new connections which would have been impossible if the sentence had a meaning. An example… sentence: "In which orbit does the electron move around the nucleus?"”

Werner Heisenberg (1901–1976) German theoretical physicist

But generally the positivistic scheme taken from mathematical logic is too narrow in a description of nature which necessarily uses words and concepts that are only vaguely defined.

“A lot of people ask the question about internet usage, "How much is too much?" Our view is it depends on how that time is spent. One of the things I feel really strongly about is there’s a lot of innovation and there’s a lot of competition, and that’s driving a lot of product improvement and a lot of usefulness and a lot of usage and also a lot of scrutiny.”

“The nature of this trade, certainly not the most honourable in the world, affords room for much investigation and remark in a moral or humane point of view: in a political or commercial light it is perhaps less conspicuously an object of attention. It consists chiefly of commodities that are considered as holding a first rate place in the animal and the mineral world, for which in return the Africans receive the most rascally articles that the ingenuity of Europeans has found means to produce. In return to our fellow creatures, for gold, and for ivory, we exchange the basest of those articles that are suited to the taste or the fancy of a despicable set of barbarians. Whether the spirituous liquirs or the fire-arms that are sent there are most calculated for the destruction of the purchasers, might become a question not very easy to determine. The noxious quality of the one is at least equalled by the danger of attending the use of the other. There does not seem to be that regard to honour in this trade, which ought to make part of the nice character of the English merchant, unimpeachable, unimpeached, upon the 'Change of London or of Amsterdam. It seems as if we kept our honour for ourselves, and that with those barbarians (who are more our inferiors in address and cunning, than perhaps in any thing else) no honour, humanity, or equity, were at all necessary.”
