"If we look into ourselves we discover propensities which declare that our intellects have arisen from a lower form; could our minds be made visible we should find them tailed."

"The philosophic spirit of inquiry may be traced to brute curiosity, and that to the habit of examining all things in search of food. Artistic genius is an expansion of monkey imitativeness."

"There is a certain class of people who prefer to say that their fathers came down in the world through their own follies rather than to boast that they rose in the world through their own industry and talents."

"We live between two worlds; we soar in the atmosphere; we creep upon the soil; we have the aspirations of creators and the propensities of quadrupeds. There can be but one explanation of this fact. We are passing from the animal into a higher form, and the drama of this planet is in its second act."

"Industry is the only true source of wealth, and there was no industry in Rome. By day the Ostia road was crowded with carts and muleteers, carrying to the great city the silks and spices of the East, the marble of Asia Minor, the timber of the Atlas, the grain of Africa and Egypt; and the carts brought nothing out but loads of dung. That was their return cargo. London turns dirt into gold. Rome turned gold into dirt."

"A religion so cheerless, a philosophy so sorrowful, could never have succeeded with the masses of mankind if presented only as a system of metaphysics. Buddhism owed its success to its catholic spirit and its beautiful morality."

"In Europe itself it is not probable that war will ever absolutely cease until science discovers some destroying force so simple in its administration, so horrible in its effects, that all art, all gallantry, will be at an end, and battles will be massacres which the feelings of mankind will be unable to endure."

"As for the system of the Commune, which makes it impossible for a man to rise or fall, it is merely the old caste system revived; if it could be put into force, all industry would be disheartened, emulation would cease, and mankind would go to sleep."

"If indeed there were a judgment-day, it would be for man to appear at the bar not as a criminal but as accuser."

"As the saints and prophets were often forced to practise long vigils and fastings and prayers before their ecstasies would fall upon them and their visions would appear, so Virtue in its purest and most exalted form can only be acquired by means of severe and long continued culture of the mind. Persons with feeble and untrained intellects may live according to their conscience; but the conscience itself will be defective. … To cultivate the intellect is therefore a religious duty; and when this truth is fairly recognized by men, the religion which teaches that the intellect should be distrusted and that it should be subservient to faith, will inevitably fall."

"What a state of society is this in which free-thinker is a term of abuse, and in which doubt is regarded as sin?"

"A day will come when the European god of the nineteenth century will be classed with the gods of Olympus and the Nile."

"The Supreme Power is not a Mind; not a Force; not a Being, but something higher than a Being; something for which we have no words, something for which we have no ideas."

"Our enlightened posterity will look back upon us who eat oxen and sheep, just as we look upon cannibals."

"And then, the Earth being small, mankind will migrate into space, and will cross the airless Saharas which separate planet from planet and sun from sun. The Earth will become a Holy Land which will be visited by pilgrims from all the quarters of the Universe. Finally, men will master the forces of Nature; they will become themselves architects of systems, manufacturers of worlds."

"All men indeed cannot be poets, inventors or philanthropists; but all men can join in that gigantic and godlike work, the progress of creation. Whoever improves his own nature improves the universe of which he is a part."

"The one, the outstanding, dramatic, imaginative, historical picture of life, to be inspired by Victorian science."

"The first rational exposition of the relations of mankind to the mystery which shrouds the how and wherefore of man’s existence."

"One book that has influenced the writer very strongly is Winwood Reade's Martyrdom of Man…It is still an extraordinarily inspiring presentation of human history as one consistent process."

"Reade was an emancipating writer because he seemed to speak as man to man to resolve history into an intelligible pattern in which there was no need for miracles. Even if he was wrong, he was grown-up."

"But when I said that nothing had been done I erred in one important matter. We had definitely committed ourselves and were halfway out of our ruts. We had put down our passage money — booked a sailing to Bombay. This may sound too simple, but is great in consequence. Until one is committed, there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiative (and creation), there is one elementary truth the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, then providence moves too. A whole stream of events issues from the decision, raising in one's favor all manner of unforeseen incidents, meetings and material assistance, which no man could have dreamt would have come his way. I learned a deep respect for one of Goethe's couplets:"

"During the anti-colonial 1960s, Livingstone was debunked: he made only one certified convert, who later backslid; he explored few areas not already traveled by others; he freed few slaves; he treated his colleagues horribly; he traveled with Arab slave traders; his family life was in shambles—in short, to many he embodied the "White Man's Burden" mentality. Nonetheless, at a time when countries are being renamed and statues are being toppled, Livingstone has not fallen. Despite modern Africans' animosity toward other Europeans, such as Cecil Rhodes, Livingstone endures as a heroic legend. Rhodesia has long since purged its name, but the cities of Livingstone (Zambia) and Livingstonia (Malawi) keep the explorer's appellation with pride."

"Dr. Livingstone, I presume?"

"The strangest disease I have seen in this country seems really to be broken-heartedness, and it attacks free men who have been captured and made slaves... Twenty one were unchained, as now safe; however all ran away at once; but eight with many others still in chains, died in three days after the crossing. They described their only pain in the heart, and placed the hand correctly on the spot, though many think the organ stands high up in the breast-bone."

"We passed a slave woman shot or stabbed through the body and lying on the path: a group of men stood about a hundred yards off on one side, and another of the women on the other side, looking on; they said an Arab who passed early that morning had done it in anger at losing the price he had given for her, because she was unable to walk any longer. 27th June 1866 - To-day we came upon a man dead from starvation, as he was very thin. One of our men wandered and found many slaves with slave-sticks on, abandoned by their masters from want of food; they were too weak to be able to speak or say where they had come from; some were quite young."

"To overdraw its evil is a simple impossibility"

"And if my disclosures regarding the terrible Ujijian slavery should lead to the suppression of the East Coast slave trade, I shall regard that as a greater matter by far than the discovery of all the Nile sources together."

"The natives are quick to detect a peculiarity in a man, and to give him a name accordingly. The conquerors of a country try to forestall them by selecting one for themselves. Susi states that when Tipo Tipo stood over the spoil taken from Nsama, he gathered it closer together, and said: "Now I am Tipo Tipo,'that is,'the gatherer together of wealth.'""

"July 29, 1869. — Went two and a half hours west to village of Ponda, where a head Arab, called by the natives 'Tipo Tipo' lives; bis name is Hamid bin Mohammed bin Juma Borajib. He presented a goat, a piece of white calico, and four big bunches of beads, also a bag of holens sorghum, and apologized because it was so little."

"The islands above the falls are covered with foliage as beautiful as can be seen anywhere. Viewed from the mass of rock which overhangs the fall, the scenery was the loveliest I had seen."

"No one can imagine the beauty of the view from anything witnessed in England. It had never been seen before by European eyes; but scenes so lovely must have been gazed upon by angels in their flight."

"Creeping with awe to the verge, I peered down into a large rent which had been made from bank to bank of the broad Zambezi, and saw that a stream of a thousand yards broad leaped down a hundred feet [30 m] and then became suddenly compressed into a space of fifteen to twenty yards."

"All I can say in my solitude is, may Heaven's rich blessing come down on every one American, English, Turk who will help to heal this open sore of the world."

"People talk of the sacrifice I have made in spending so much of my life in Africa. Can that be called a sacrifice which is simply paid back as a small part of a great debt owing to our God, which we can never repay? Is that a sacrifice which brings its own blest reward in healthful activity, the consciousness of doing good, peace of mind, and a bright hope of a glorious destiny hereafter? Away with the word in such a view and with such a thought! It is emphatically no sacrifice. Say rather it is a privilege. Anxiety, sickness, suffering, or danger now and then with a foregoing of the common conveniences and charities of this life, may make us pause and cause the spirit to waver and the soul to sink; but let this only be for a moment. All these are nothing when compared with the glory which shall be revealed in and for us. I never made a sacrifice."
