Asking oneself and others what the perfect version of something is, the ideal version, might sound like a strange idea.

What is the perfect marriage or career or system of government or school?

It can feel immature and naive to bother much with such questions.

They're just daydreams.

After all, who cares about ideal versions?

We might as well deal with with what we've got.

But the great ancient

Greek philosopher Plato strenuously disagrees with this.

Throughout his work, he argues

that focusing on the ideal version of something is one of the most useful kinds of thought exercises we can generate.

It's by knowing what we think something should be like

that we can more clearly start to define what might be wrong

and focus on what we need to do to make the world slightly better.

When he was talking about ideals, Plato used a slightly strange but ultimately rather useful word – the forms.

So he asked not what is the ideal friendship or the ideal kind of parental love,

he asked what is the form of friendship or the form of parental love.

It does sound strange but what he had in mind was something very practical.

When a Greek stonemason was carving an ornament, they wouldn't just make it up themselves,

they'd make use of a wooden template or form to check if they were getting it right.

The form itself was made by the master, but if the mason possessed the form, they could more reliably do perfect work.

This is Plato's basic picture of what an ideal is.

It's the guide you need that shows you how to do something well yourself.

If you've got possession of the form, you can be guided towards a true goal.

A form, as Plato sees it, is a blueprint, a set of instructions for making a very good version of something.

That's why we all need a well -thought -through set of forms to guide us in life.

And unsurprisingly, it is philosophy that can guide us to these forms.

So, for example, the form of friendship is a mental model of what a really good friendship actually involves.

And if you grasp this model, if this idea is active in your mind, you will know how to be a good friend.

Similarly, having a form of education in mind is going to be very useful for the teacher.

– it'll stop her being buffeted by events and day -to -day pressures – she'll be able to keep in mind where,

ideally, she should be going.

We've typically thought of ideals as fantasy projections that blithely ignore most of what life is actually like.

We think of them as the opposite of being realistic.

But Plato sees an ideal as the result of a deep understanding and careful engagement with reality.

Someone setting up an airport would need in the platonic scheme to have in mind the ideal air traffic control system,

something optimally effective, efficient and safe.

This is the person who would, in Plato's terms, have grasped the form of air traffic control.

We all need to have as many forms in mind as we possibly can.

Plato is breaking the habitual assumption

that searching for the ideal is at odds with getting things done in the rough and tumble of the real world.

And he's pushing us to be more exacting about where we are trying to head to.

If an ideal seems utterly distant and hopeless, maybe the problem isn't that it's too idealistic,

but in a strange but important way, actually not idealistic enough.

That is, we've not quite yet discovered the form.

We shouldn't abandon our ideals.

We should get more ambitious about them and Plato's philosophy is on hand to help us.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
