“It often turns out on closer inspection that acts of apparent altruism are really selfishness in disguise.”

On the character "Thunder Jim Wade" in "The Poison People" in Thrilling Adventures (July 1941) using the pseudonym "Charles Stoddard."
Short fiction
Context: A casual eye might have seen nothing extraordinary in Wade as he moved lithely across the meadow toward the Thunderbug. He was tall, lean and rangy, looking rather like a college boy on a vacation, with his brown, almost youthful face and tousled dark hair, so deep-black that it was almost blue.
A closer inspection would have shown more significant details. There was an iron hardness underlying Wade’s face, like iron beneath velvet. His jet eyes were decidedly not those of a boy. There was a curious quality of soft depth to them, although sometimes that black deep could freeze over with deadly purpose.

Context: It is to be regretted that the rich and powerful too often bend the acts of government to their selfish purposes. Distinctions in society will always exist under every just government. Equality of talents, of education, or of wealth can not be produced by human institutions. In the full enjoyment of the gifts of Heaven and the fruits of superior industry, economy, and virtue, every man is equally entitled to protection by law; but when the laws undertake to add to these natural and just advantages artificial distinctions, to grant titles, gratuities, and exclusive privileges, to make the rich richer and the potent more powerful, the humble members of society — the farmers, mechanics, and laborers — who have neither the time nor the means of securing like favors to themselves, have a right to complain of the injustice of their government. There are no necessary evils in government. Its evils exist only in its abuses. If it would confine itself to equal protection, and, as Heaven does its rains, shower its favors alike on the high and the low, the rich and the poor, it would be an unqualified blessing.
