It concerns the opinion of Naudin and Darwin that a single pollen grain does not suffice for fertilization of the ovule. I used Mirabilis Jalappa for an experimental plant, as Naudin had done; the result of my experiment is, however, completely different. From fertilizations with single pollen grains, I obtained eighteen well-developed seeds, and from these an equal number of plants, of which ten are already in bloom.

An extra-terrestrial philosopher, who had watched a single youth up to the age of twenty-one and had never come across any other human being, might conclude that it is the nature of human beings to grow continually taller and wiser in an indefinite progress towards perfection and this generalization would be just as well founded as the generalization which evolutionists base upon the previous history of this planet.
Bertrand Russell
Love, n. A temporary insanity curable by marriage or by removal of the patient from the influences under which he incurred the disorder. This disease, like caries and many other ailments, is prevalent only among civilized races living under artificial conditions; barbarous nations breathing pure air and eating simple food enjoy immunity from its ravages. It is sometimes fatal, but more frequently to the physician than to the patient.
Ambrose Bierce
We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.
Marie Curie
How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.
Arthur Schopenhauer
My poor soul! Sigh, pray and strive to take upon you the blessed yoke of Christ, and you will live on earth in a heavenly manner. Lord, grant that I may carry the light and goodly yoke, and I shall be always at rest, peaceful, glad and joyous; and I shall taste on earth of crumbs which fall from the celestial feast, like a dog that feeds upon the crumbs which fall from the master's table.
Tikhon of Zadonsk
