Knowledge of our Capacity a cure of Scepticism and Idleness.       §6. When we know our own Strength, we shall the better know
what to undertake with hopes of Success: And when we have well
survey’d the Powers of our own Minds, and made some Estimate
what we may expect from them, we shall not be inclined either to sit
still, and not set our Thoughts on work at all, in Despair of know-
ing any thing; nor on the other side question every thing, and dis-
claim all Knowledge, because some Things are not to be understood.
’Tis of great use to the Sailor to know the length of his Line, though
he cannot with it fathom all the depths of the Ocean. ’Tis well he
knows, that it is long enough to reach the bottom, at such Places,
as are necessary to direct his Voyage, and caution him against
running upon Shoals, that may ruin him. Our Business here is not to
know all things, but those which concern our Conduct. If we can
find out those Measures, whereby a rational Creature put in that
State, which Man is in, in this World, may, and ought to govern his
Opinions, and Actions depending thereon, we need not be troubled,
that some other things escape our Knowledge.
Locke Hum I, 1, §6, p. 46
