Quote #1
When Pericles, the great Athenian statesman and general, was on his death-bed, his surrounding friends [...] began to indulge their sorrow for their expiring patron, by enumerating his great qualities and successes, his conquests and victories, the unusual length of his administration, and his nine trophies [...] You forget, cries the dying hero [...] the most eminent of my praises [...] You have not observed that no citizen has ever yet worne mourning on my account. (II.I.2)
Near the end of the Enquiry, Hume says that natural pleasures are way more valuable than possessions or any other stuff. From this quote, it would appear that Pericles had a similar view. When he was dying, his pals starting harping about his conquests and trophies, but, in his eyes, the fact that he'd caused no suffering to his citizens was much more important. See, this dude knew what really mattered.
Quote #2
Were there a species of creatures intermingled with men, which, though rational, were possessed of such inferior strength, both of body and mind, that they were incapable of all resistance [...] the necessary consequence, I think, is that we should be bound by the laws of humanity to give gentle usage to these creatures, but should not […] lie under any restraint of justice with regard to them, nor could they possess any right or property, exclusive of such arbitrary lords. (III.I.18)
In this quote, Hume chews on an imaginary situation: what if we lived alongside creatures that were rational and pleasant but had nowhere near our level of physical or mental strength? Hume's take is that we wouldn't subject them to tasks that they weren't fit for; however, we wouldn't give them the same property rights that we enjoy or feel that we were bound to them through systems of justice. In short, it wouldn't be an equal arrangement, but us humans have never been too good at the whole equality thing. Just look at racism.
Quote #3
The tortoise, according to the fable, by his perseverance, gained the race of the hare, though possessed of much superior swiftness. A man's time, when well husbanded, is like a cultivated field, of which a few acres produce more of what is useful to life, than extensive provinces, even of the richest soil, when over-run with weeds and brambles. (VI.I.10)
Fables are great for teaching us valuable life lessons, and the one about the tortoise and the hare is as well-known today as it was in Hume's time. Just in case it's somehow flown under your radar, its point is that being cautious and careful can pay off in the long run, whereas going headfirst into situations at full speed may not work out. It's about using our time wisely and thinking about what's practical and valuable.
