"First, anyone who seriously intends to become a philosopher

Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge.

The maturity of man-that means, to have reacquired the seriousness that one had as a child at play

Many of our most serious conflicts are conflicts within ourselves. Those who suppose their judgements are always consistent are unreflective or dogmatic.

What we have forgotten is that thoughts and words are conventions, and that it is fatal to take conventions too seriously. A convention is a social convenience, as, for example, money ... but it is absurd to take money too seriously, to confuse it with real wealth ... In somewhat the same way, thoughts, ideas and words are "coins" for real things.

Man suffers only because he takes seriously what the Gods made for fun.

A serious and good philosophical work could be written consisting entirely of jokes.

So let me get this straight. You were living in a tent in the woods, but now you're living with Prince Charming and anger management boy? SERIOUSLY?!

"You are putting yourself in serious danger...'

Good-humor is a philosophic state of mind; it seems to say to Nature that we take her no more seriously than she takes us. I maintain that one should always talk of philosophy with a smile.

There are things that are so serious that you can only joke about them.

"You're not eating anything," said Marilla sharply, eying her as if it were a serious shortcoming. Anne sighed.

It's so hard to believe in anything anymore. I mean, it's like, religion, you really can't take it seriously, because it seems so mythological, it seems so arbitrary...but, on the other hand, science is just pure empiricism, and by virtue of its method, it excludes metaphysics. I guess I wouldn't believe in anything anymore if it weren't for my lucky astrology mood watch.

Humor can get in under the door while seriousness is still fumbling at the handle.

Humor is also a way of saying something serious.

She wasn't the only one to be physically morphed by reader expectation. Miss Havisham was now elderly whether she liked it or not, and Sherlock Holmes wore a deerstalker and smoked a ridiculously large pipe. The problem wasn't just confined to the classics. Harry Potter was seriously pissed off that he'd have to spend the rest of life looking like Daniel Radcliffe.

Most helmsmen would've been satisfied with a pilot's wheel or a tiller. Leo had also installed a keyboard, monitor, aviation controls from a Learjet, a dubstep soundboard, and motion-control sensors from a Nintendo Wii. He could turn the ship by pulling on the throttle, fire weapons by sampling an album, or raise sails by shaking his Wii controllers really fast. Even by demiGod standards, Leo was seriously ADHD.

There were people who believed their opportunities to live a fulfilled life were hampered by the number of Asians in England, by the existance of a royal family, by the volume of traffic that passed by their house, by the malice of trade unions, by the power of callous employers, by the refusal of the health service to take their condition seriously, by communism, by capitalism, by atheism, by anything, in fact, but their own futile, weak-minded failure to get a fucking grip.

I watched a lot of YouTube videos of cute geeky girls playing '80s cover tunes on ukuleles. Technically, this wasn't part of my research, but I had a serious cute-geeky-girls-playing-ukuleles fetish that I can neither explain nor defend.

No one believes you're serious until bodies start to fall. -Vlad

Okay, seriously, I dont know if this is true or not, but I heard people who use profanity are trying to compensate for their lack of you know... size" -Tuck

Oh for craps sake. You're not dying again, are you? It's seriously inconvenient when you do that." -Aphrodite

"...I doubt very seriously whether anyone will hire me.'

Obviously, if I was serious about having a relationship with someone long-term, the last people I would introduce him to would be my family.
