A Quote by Charles Heiser on agriculture, animals, argument, certainty, change, discipline, existence, food, leisure, life, plants, seasons, and time

Agriculture probably required a far greater discipline than did any form of food collecting. Seeds had to be planted at certain seasons, some protection had to be given to the growing plants and animals, harvests had to be reaped, stored and divided. Thus, we might argue that it was neither leisure time nor a sedentary existence but the more rigorous demands associated with an agricultural way of life that led to great cultural changes.

A Quote by Celia Thaxter on certainty, children, earth, happiness, innocence, joy, musicians, poets, rest, tears, and tranquility

Like the musician, the painter, the poet, and the rest, the true lover of flowers is born, not made. And he is born to happiness in this vale of tears, to a certain amount of the purest joy that earth can giver her children, joy that is tranquil, innocent, uplifting, unfailing.

A Quote by Carl Gustav Jung on certainty, impossibility, life, and problems

The greatest and most impossible problems of life are all in a certain sense insoluble. They can never be solved but only outgrown.

A Quote by Carl G. Hempel on certainty, doubt, fame, mathematics, necessity, and science

The most distinctive characteristic which differentiates mathematics from the various branches of empirical science, and which accounts for its fame as the queen of the sciences, is no doubt the peculiar certainty and necessity of its results.

A Quote by Carl G. Hempel on bachelors, certainty, contentment, information, mathematics, and sharing

The propositions of mathematics have, therefore, the same unquestionable certainty which is typical of such propositions as "All bachelors are unmarried," but they also share the complete lack of empirical content which is associated with that certainty: The propositions of mathematics are devoid of all factual content; they convey no information whatever on any empirical subject matter.

A Quote by Brutus Hamilton on achievement, certainty, discipline, envy, goals, life, men, order, pity, pleasure, and work

It is one of the strange ironies of this strange life that those who work the hardest, who subject themselves to the strictest discipline, who give up certain pleasurable things in order to achieve a goal, are the happiest men. When you see 20 or 30 men line up for a distance race in some meet, don't pity them, don't feel sorry for them. Better envy them instead."

A Quote by Bryan S. W. Green on attitude, certainty, christianity, church, god, mind, opportunity, organize, spirit, present, and world

Evangelism is not an activity at all. It is rather an attitude of mind behind all Christian activity. Evangelism is not a list of certain things done, but the spirit in which they are done. That is precisely why it cannot be organized. It is perhaps best described as an attitude of mind towards God and the world - an attitude which the Church must recover if she is to be true to her Lord, and to seize hold of the present opportunity.
