Obstinacy is will asserting itself without being able to justify itself. It is persistence without a reasonable motive. It is the tenacity of self-love substituted for that of reason and conscience.
...there is a difference between being convinced and being stubborn. I’m not certain what the difference is, but I do know that if you butt your head against a stone wall long enough, at some point you realize the wall is stone and that your head is flesh and blood.
Said in 1979, on giving up her attempt to be named director of the television version of the first volume of her autobiography, "I Know Why the Caged Bird Sings"
Man is not logical and his intellectual history is a record of mental reserves and compromises. He hangs on to what he can in his old beliefs even when he is compelled to surrender their logical basis.
"Brutes find out where their talents lie;
A bear will not attempt to fly,
A foundered horse will oft debate
Before he tries a five barred gate.
A dog by instinct turns aside
Who sees the ditch too deep and wide,
But man we find the only creature
Who, led by folly, combats nature;
Who, when she loudly cries—Forbear!
With obstinacy fixes there;
And where the genius least inclines,
Absurdly bends his whole designs."
