Hobbes: What it is to lay down a right

What it is to lay down a Right
To Lay Downe a mans Right to any thing, is to Devest himselfe
of the Liberty, of hindring another of the benefit of his own
Right to the same. For he that renounceth, or passeth away his Right,
giveth not to any other man a Right which he had not before;
because there is nothing to which every man had not Right by Nature:
but onely standeth out of his way, that he may enjoy his own
originall Right, without hindrance from him; not without hindrance
from another. So that the effect which redoundeth to one man,
by another mans defect of Right, is but so much diminution of
impediments to the use of his own Right originall.

Thomas Hobbes, "The Leviathan." Chapter XIV

Hobbes on Want of Understanding

Ignorance of the signification of words; which is, want of
understanding, disposeth men to take on trust, not onely the
truth they know not; but also the errors; and which is more,
the non-sense of them they trust: For neither Error, nor non-sense,
can without a perfect understanding of words, be detected.

(p.61) Hobbes "Leviathan"

This seems like such a patently obvious statement, but failure to understand this follows us around for entire lifetimes. Essentially, we trust nonsense.

Hobbes on lack of timely resolution

Timely Resolution, or determination of what a man is to do,
is Honourable; as being the contempt of small difficulties, and dangers.
And Irresolution, Dishonourable; as a signe of too much valuing of
little impediments, and little advantages: For when a man has weighed
things as long as the time permits, and resolves not, the difference
of weight is but little; and therefore if he resolve not,
he overvalues little things, which is Pusillanimity.

Hobbes: Leviathan (1651), p.55 of my version of the Gutenberg e-text.
Chapter X: "Of Power, Worth, Dignity, Honour and Worthiness"

Lack of timely resolution is a sign of too much focus on little impediments and little advantages. Hobbes claims that lack of courage or determination lies at the core of this inaction. Hobbes repeats this idea in Chapter XI:

Irresolution, From Too Great Valuing Of Small Matters
Pusillanimity disposeth men to Irresolution, and consequently
to lose the occasions, and fittest opportunities of action.
For after men have been in deliberation till the time of
action approach, if it be not then manifest what is best to be done,
tis a signe, the difference of Motives, the one way and the other,
are not great: Therefore not to resolve then, is to lose the occasion
by weighing of trifles; which is pusillanimity.
