Shades of meaning
Fernald has no entry of its own for self-esteem; he lists it under egotism, pride.
Where he writes about it:
Self-esteem is more solid and better founded than self-conceit; but is ordinarily a weakness, and never has the worthy sense of self-confidence. — from egotism
Self-respect is a thoroughly worthy feeling; self-esteem is a more generous estimate of one's own character and abilities than the rest of the world are ready to allow. — from pride
