Who said: “The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it... That is how we will preserve our planet, commanded to our care by God. That’s what will lend meaning to the creed our fathers once declared.”

Left Quotes (13 quotes)

A prolonged war in which a nation takes part is bound to impoverish the breed, since the character of the breed depends on the men who are left.
As given in David Starr Jordan, War and the Breed: The Relation of War to the Downfall of Nations (1915), 178.

All in all, the total amount of power conceivably available from the uranium and thorium supplies of the earth is about twenty times that available from the coal and oil we have left.
In The Intelligent Man's Guide to Science: The physical sciences (1960), 371.

However much the pits may be apparent, yet none, as far as can be comprehended by the senses, passes through the septum of the heart from the right ventricle into the left. I have not seen even the most obscure passages by which the septum of the ventricles is pervious, although they are mentioned by professors of anatomy since they are convinced that blood is carried from the right ventricle into the left. As a result—as I shall declare more openly elsewhere—I am in no little doubt regarding the function of the heart in this part.
In De Humani Corporis Fabrica Libri Septem [Seven Books on the Structure of the Human Body] (revised ed. 1555), 734. Quoted and trans. in Charles Donald O'Malley, Andreas Vesalius of Brussels, 1514-1564 (1964), 281.

If I have put the case of science at all correctly, the reader will have recognised that modern science does much more than demand that it shall be left in undisturbed possession of what the theologian and metaphysician please to term its “legitimate field.” It claims that the whole range of phenomena, mental as well as physical—the entire universe—is its field. It asserts that the scientific method is the sole gateway to the whole region of knowledge.
From The Grammar of Science (1892), 29-30.
Science quotes on:  |  Assertion (23)  |  Case (64)  |  Claim (52)  |  Correction (28)  |  Demand (52)  |  Field (119)  |  Gateway (3)  |  Knowledge (1128)  |  Legitimate (8)  |  Metaphysician (4)  |  Mind (544)  |  Modern Science (10)  |  Phenomenon (218)  |  Possession (37)  |  Range (38)  |  Reader (22)  |  Recognition (62)  |  Region (26)  |  Science (1699)  |  Scientific Method (155)  |  Sole (9)  |  Term (87)  |  Theologian (14)  |  Universe (563)  |  Whole (122)

If someone separated the art of counting and measuring and weighing from all the other arts, what was left of each (of the others) would be, so to speak, insignificant.
Plato
Philebus 55e. Trans. R. W. Sharples.

If that's how it all started, then we might as well face the fact that what's left out there is a great deal of shrapnel and a whole bunch of cinders (one of which is, fortunately, still hot enough and close enough to be good for tanning). Trying to find some sense and order in this mess may be as futile as trying to … reconstruct the economy of Iowa from a bowl of popcorn. [On searching for evidence of the Big Bang.]
From essay 'First Person Secular: Blocking the Gates to Heaven', Mother Jones Magazine (Jun 1986), 48. Collected in The Worst Years of our Lives: Irreverent Notes from a Decade of Greed (1995), 267.

If the mysterious influence to which the dissymmetry of nature is due should come to change in sense or direction, the constituting elements of all living beings would take an inverse dissymmetry. Perhaps a new world would be presented to us. Who could foresee the organization of living beings, if the cellulose, which is right, should become left, if the left albumen of the blood should become right? There are here mysteries which prepare immense labours for the future, and from this hour invite the most serious meditations in science.
Lecture (3 Feb 1860), to the Chemical Society of Paris, 'On the Molecular Dissymetry of Natural Organic Products', reprinted in The Chemical News and Journal of Industrial Science (3 May 1862), 5, No. 126, 248.

It is incumbent upon us to keep training and pruning the tree of knowledge without looking to the right or the left.
From United States Bureau of Animal Industry, 'Investigations of Diseases of Domesticated Animals', Annual Report: Fiscal Years 1895 and 1896 (1897), Vol. 12, 150.

It is probable that all organisms now alive are descended from one ancestor, for the following reason. Most of our structural molecules are asymmetrical, as shown by the fact that they rotate the plane of polarized light, and often form asymmetrical crystals. But of the two possible types of any such molecule, related to one another like a right and left boot, only one is found throughout living nature. The apparent exceptions to this rule are all small molecules which are not used in the building of the large structures which display the phenomena of life.
In 'The Origin of Life', The Inequality of Man: And Other Essays (1932), 157.

Religion is something left over from the infancy of our intelligence, it will fade away as we adopt read on and science as our guidelines.

Since men are really interested in nothing but their own opinions, every one who puts forward an opinion looks about him right and left for means of strengthening himself and others in it.
In The Maxims and Reflections of Goethe (1906), 193.

There was rock to the left and rock to the right, and low lean thorn between
And thrice he heard a breech bolt snick, tho never a man was seen.
In 'Ballad of East and West', Ballads and Barrack-Room Ballads (1893), 6.
Science quotes on:  |  Lean (6)  |  Low (16)  |  Right (144)  |  Rock (107)  |  Thorn (5)

What would the world be, once bereft
Of Wet and Wilderness? Let them be left,
O let them be left, wilderness and wet;
Long live the weeds and the wilderness yet.
'Inversnaid' (1881), reprinted in Gerard Manley Hopkins and Michael White (ed.) Some Poems of Gerard Manley Hopkins, (1945), 16, stanza 4.
Science quotes on:  |  Weed (14)  |  Wet (5)  |  Wilderness (28)


Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
