The proper study of mankind is the science of design.

I put for the general inclination of all mankind a perpetual and restless desire of power after power that ceaseth only in death.

Property is unstable and youth perishes in a moment. Life itself is held in the grinning fangs of Death Yet men delay to obtain release from the world. Alas the conduct of mankind is surprising.

A man may devote himself to death and destruction to save a nation but no nation will devote itself to death and destruction to save mankind.

It is impossible that anything so natural so necessary and so universal as death should ever have been designed by providence as an evil to mankind.

Creation destroys as it goes throws down one tree for the rise of another. But ideal mankind would abolish death multiply itself million upon million rear up city upon city save every parasite alive until the accumulation of mere existence is swollen to a horror.

Any man's death diminishes me because I am involved in Mankind And therefore never send to know for whom the bell tolls it tolls for thee.

To show the world what long experience gains requires not courage though it calls for pains but at life's outset to inform mankind is a bold effort of a valiant mind.

For this equilibrium now in sight let us trust that mankind as it has occurred in the greatest periods of its past will find for itself a new code of ethics common to all made of tolerance of courage and of faith in the Spirit of men.

Art must unquestionably have a social value that is as a potential means of communication it must be addressed and in comprehensible terms to the understanding of mankind.

A great revolution in just one single individual will help achieve a change in the destiny of a society and further will enable a change in the destiny of humankind.

The joy of life consists in the exercise of one's energies continual growth constant change the enjoyment of every new experience. To stop means simply to die. The eternal mistake of mankind is to set up an attainable ideal.

When I climb into my car I enter my destination into a GPS device whose spatial memory supplants my own. I have photographs to store the images I want to remember books to store knowledge and now thanks to Google I rarely have to remember anything more than the right set of search terms to access humankind's collective memory.

It all happened so fast. The ghetto. The deportation. The sealed cattle car. The fiery altar upon which the history of our people and the future of mankind were meant to be sacrificed.

No illusion is more crucial than the illusion that great success and huge money buy you immunity from the common ills of mankind such as cars that won't start.

The work of the individual still remains the spark that moves mankind ahead even more than teamwork.

How mankind defers from day to day the best it can do and the most beautiful things it can enjoy without thinking that every day may be the last one and that lost time is lost eternity!

The best security for civilization is the dwelling and upon properly appointed and becoming dwellings depends more than anything else the improvement of mankind.

I find myself hoping a total end of all the unhappy divisions of mankind by party-spirit which at best is but the madness of many for the gain of a few.

We have the power to make this the best generation of mankind in the history of the world or to make it the last.

Mankind's true moral test its fundamental test (which lies deeply buried from view) consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle a debacle so fundamental that all others stem from it.

The person who knows one thing and does it better than anyone else even if it only be the art of raising lentils receives the crown he merits. If he raises all his energy to that end he is a benefactor of mankind and its rewarded as such.

No heirloom of humankind captures the past as do art and language.

For many years I have lived uncomfortably with the belief that most planning and architectural design suffers for lack of real and basic purpose. The ultimate purpose it seems to me must be the improvement of mankind.
