Simon was hot-headed, impulsive, rash, unstable.
"The Expositor's Bible: The Gospel of St. John, Vol. I"
Marcus Dods
A few lessons in good husbandry will do much more for the comfort of a people than many changes of social organization; but good husbandry is virtually impossible under a system of unstable tenure, which turns a man necessarily out of his holding every few years for the purpose of a new distribution of the land, and which compels him to take his holding, when he gets it, in some thirty or forty scattered plots.
"Contemporary Socialism"
John Rae
No it was the certainty that we poor mortals can have no firm and steadfast support in this unstable world.
"The Dead Lake and Other Tales"
Paul Heyse
