There is nothing in this world that I fear to say.

The most all penetrating spirit before which will open the possibility of tilting not tables, but planets, is the spirit of free human inquiry. Believe only in that.

Work, look for peace and calm in work: you will find it nowhere else.

I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.

Knowing how contented, free, and joyful is life in the world of science, one fervently wishes that many would enter its portals.

Certain characteristic properties of elements can be foretold from their atomic weights.

The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.

No one nor anything can silence me.

There exists everywhere a medium in things, determined by equilibrium.

Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).

If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law of periodicity.

Humanity's moral conscience progresses, slowly yet surely...

Anytime someone says your God is ugly and you release your God and join their God, there is no hope for your freedom until you once more believe in your own concept of the 'deity.'

How do you keep cheer when you go from beautiful to bald in three days?

I'll Stay ...leave ...me. ...I'll ...follow ...you.

But words are vain; reject them all— They utter but a feeble part: Hear thou the depths from which they call, The voiceless longing of my heart.

You'll never make America great again, [Donald] Trump, but you can extend her time.

Your eyes are windows to your dreams; Your ears are windows to your mind; You nose is the door to your heart - you can win over any man with just your smell.

Dogs really are perfect soldiers. They are brave and smart; they can smell through walls, see in the dark, and eat Army rations without complaint.

Everybody is changing.

When we run out of money, we have to start thinking.
