Echoes

History is largely a record of human behavior, and human behavior has not greatly changed.

That which comes after ever conforms to that which has gone before.

Human nature being what it is, events which happened in the past will at some time or other and in much the same ways be repeated in the future.

Everything changes; nothing perishes.

Mankind are so much the same, in all times and places, that history informs us of nothing new or strange in this particular. Its chief use is only to discover the constant and universal principles of human nature.

No man ever steps in the same river twice, for it is not the same river and he is not the same man.

Whoever wishes to foresee the future must consult the past; for human events ever resemble those of preceding times. This arises from the fact that they are produced by men who ever have been, and ever shall be, animated by the same passions, and thus they necessarily have the same results.

Everything is interaction and reciprocal.

In the great chain of causes and effects, no single fact can be considered in isolation.

What once sprung from the earth sinks back into the earth.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

The scenes of life are like the pictures in a magic lantern: we see them, one after another, with vivid distinctness; but as soon as one vanishes, it is utterly forgotten; and then the next appears, completely different from what went before — though at bottom it is always the same story.

From the heights of these pyramids, forty centuries look down on us.

Life can only be understood backwards; but it must be lived forwards.

The only certainty is that nothing is certain.

If I have seen further it is by standing on ye sholders of Giants.

The sun is new each day.

Time present and time past are both perhaps present in time future, and time future contained in time past.

A part of good science is to see what everyone else can see but think what no one else has ever said.

I felt before I thought: this is the common lot of humanity.

From nothing comes nothing. Nothing that exists can be destroyed. All changes are due to the combination and separation of atoms.

You are not a drop in the ocean. You are the entire ocean, in a drop.

It isn't all over; everything has not been invented; the human adventure is just beginning.

It is not truth that makes man great, but man that makes truth great.

Every day is a journey, and the journey itself is home.
