All pain is per se and especially in excess, destructive and ultimately fatal in its nature and effects.
James Young Simpson
Everything in excess is opposed to nature.
Hippocrates
Nature is ever at work building and pulling down, creating and destroying, keeping everything whirling and flowing, allowing no rest but in rhythmical motion, chasing everything in endless song out of one beautiful form into another.
John Muir
Prodigality is the vice of a weak nature, as avarice is of a strong one.It comes of a weak craving for those blandishments of the world which are easily had for money.
Sir Henry Taylor
Prodigality is indeed the vice of a weak nature, as avarice is of a strong one; it comes of a weak craving for those blandishments of the world which are easily to be had for money.
Sir Henry Taylor
Climb the mountains and get their good tidings. Nature's peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy, while cares will drop off like autumn leaves.
John Muir
For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver.
Martin Luther

England has always been disinclined to accept human nature.
E. M. Forster
The royal throne of kings, this scepter'd isle, This earth of majesty, this seat of Mars, This other Eden, demi-paradise, This fortress built by nature for herself Against infection and the hand of war; This happy breed of men, this little world, This precious stone set in the silver sea.
William Shakespeare
The survival of the fittest is the ageless law of nature, but the fittest are rarely the strong. The fittest are those endowed with the qualifications for adaptation, the ability to accept the inevitable and conform to the unavoidable, to harmonize with existing or changing conditions.
Dave E. Smalley
Vegetarian food leaves a deep impression on our nature. If the whole world adopts vegetarianism, it can change the destiny of humankind.
Albert Einstein
Nature has always had more force than education.
Voltaire
Engineers participate in the activities which make the resources of nature available in a form beneficial to man and provide systems which will perform optimally and economically.
L. M. K. Boelter
Good men, whether they be Christians or rationalists, do not desire to discriminate between races, but the distinctions implanted by Nature are too conspicuous to escape the observation of our senses.
