“This you may say of man – when theories change and crash, when schools, philosophies, when narrow dark alleys of thought, national, religious, economic, grow and disintegrate, man reaches, stumbles forward, painfully, mistakenly, sometimes. Having stepped forward, he may slip back, but only half a step, never the full step back. This you may say and know it and know it”
The Grapes of Wrath, John Steinbeck
