Alteration Quotes - page 2
Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.
Lynn Margulis
I have chosen my boat, and laid in my scant stores. I have selected a few books; the principal are Homer and Shakespeare - But the libraries of the world are thrown open to me - and in any port I can renew my stock. I form no expectation of alteration for the better; but the monotonous present is intolerable to me. Neither hope nor joy are my pilots - restless despair and fierce desire of change lead me on. I long to grapple with danger, to be excited by fear, to have some task, however slight or voluntary, for each day's fulfilment. I shall witness all the variety of appearance, that the elements can assume - I shall read fair augury in the rainbow - menace in the cloud - some lesson or record dear to my heart in everything. Thus around the shores of deserted earth, while the sun is high, and the moon waxes or wanes, angels, the spirits of the dead, and the ever-open eye of the Supreme, will behold the tiny bark, freighted with Verney - the LAST MAN.
Mary Shelley
Habit... makes the endurance of evil easy (which, under the name of patience, is falsely honored as a virtue), because sensations of the same type, when continued without alteration for a long time, draw our attention away from the senses so that we are scarcely conscious of them at all. On the other hand, habit also makes the consciousness and the remembrance of good that has been received more difficult, which then gradually leads to ingratitude (a real vice). [...] Acquired habit deprives good actions of their moral value because it undermines mental freedom and, moreover, it leads to thoughtless repetitions of the same acts (monotony), and thus becomes ridiculous.
Immanuel Kant
Many facts have lately transpired which tend to overthrow the hypothesis that heat is itself a body, and to prove that it consists in a motion of the ultimate particles of bodies. If this be so, the general principles of mechanics may be applied to heat; this motion may be converted into work, the loss of vis viva in each particular case being proportional to the quantity of work produced.
These circumstances, of which Carnot was also well aware, and the importance of which he expressly admitted, pressingly demand a comparison between heat and work, to be undertaken with reference to the divergent assumption that the production of work is not only due to an alteration in the distribution of heat, but to an actual consumption thereof; and inversely, that by the expenditure of work, heat may be produced.
Rudolf Clausius
