Interesting. Ok, maybe
liberal is young peoples' philosophy,
conservative is old peoples'. As reflected in the many sayings about how you should be the former before 30 or 40, the latter afterwards. It's not more
natural to be young or old - both are natural. From Robert Louis Stevenson:
"...the opinions of old men about life have been accepted as final. All sorts of allowances are made for the illusions of youth; and none, or almost none, for the disenchantments of age. It is held to be a good taunt, and somehow or other to clinch the question logically, when an old gentleman waggles his head and says: “Ah, so I thought when I was your age.” It is not thought an answer at all, if the young man retorts: “My venerable sir, so I shall most probably think when I am yours.”
Because I have reached Paris, I am not ashamed of having passed through Newhaven and Dieppe. They were very good places to pass through, and I am none the less at my destination. All my old opinions were only stages on the way to the one I now hold, as itself is only a stage on the way to something else. I am no more abashed at having been a red-hot Socialist with a panacea of my own than at having been a sucking infant. Doubtless the world is quite right in a million ways; but you have to be kicked about a little to convince you of the fact. And in the meanwhile you must do something, be something, believe something. It is not possible to keep the mind in a state of accurate balance and blank; and even if you could do so, instead of coming ultimately to the right conclusion, you would be very apt to remain in a state of balance and blank to perpetuity. Even in quite intermediate stages, a dash of enthusiasm is not a thing to be ashamed of in the retrospect: if St. Paul had not been a very zealous Pharisee, he would have been a colder Christian. For my part, I look back to the time when I was a Socialist with something like regret. I have convinced myself (for the moment) that we had better leave these great changes to what we call great blind forces: their blindness being so much more perspicacious than the little, peering, partial eyesight of men. I seem to see that my own scheme would not answer; and all the other schemes I ever heard propounded would depress some elements of goodness just as much as they encouraged others. Now I know that in thus turning Conservative with years, I am going through the normal cycle of change and travelling in the common orbit of men’s opinions. I submit to this, as I would submit to gout or gray hair, as a concomitant of growing age or else of failing animal heat; but I do not acknowledge that it is necessarily a change for the better — I daresay it is deplorably for the worse. I have no choice in the business, and can no more resist this tendency of my mind than I could prevent my body from beginning to totter and decay. ...
When the old man waggles his head and says, “Ah, so I thought when I was your age,” he has proved the youth’s case. Doubtless, whether from growth of experience or decline of animal heat, he thinks so no longer; but he thought so while he was young; and all men have thought so while they were young, since there was dew in the morning or hawthorn in May; and here is another young man adding his vote to those of previous generations and rivetting another link to the chain of testimony. It is as natural and as right for a young man to be imprudent and exaggerated, to live in swoops and circles, and beat about his cage like any other wild thing newly captured, as it is for old men to turn gray, or mothers to love their offspring, or heroes to die for something worthier than their lives."
