To Act Is Easy, To Think Is

The Person Who In Shaky Times Also Wavers Only Increases The Evil, But The Person Of Firm Decision Fashions The Universe.

Should I Not Be Proud, When For Twenty Years I Have Had To Admit To Myself That The Great Newton And All The Mathematicians And Noble Calculators Along With Him Were Involved In A Decisive Error With Respect To The Doctrine Of Color, And That I Among Millions Was The Only One Who Knew What Was Right In This Great Subject Of Nature?

People Will Allow Their Faults To Be Shown Them; They Will Let Themselves Be Punished For Them; They Will Patiently Endure Many Things Because Of Them; They Only Become Impatient When They Have To Lay Them Aside.

The Really Unhappy Person Is The One Who Leaves Undone What They Can Do, And Starts Doing What They Don't Understand; No Wonder They Come To Grief.

Nothing Will Change The Fact That I Cannot Produce The Least Thing Without Absolute Solitude.
