Can you love someone you have never met in person (for example, a pen pal or an online friend)? Is this connection as strong as a "real-life" one?

Yes. Meeting in person or not is only a matter of forms. But sometimes I feel unrealistic about it and we human are born to tend to have a real-life experience. 

Quote of the Week: "Love is composed of a single soul inhabiting two bodies." - Aristotle. Do you agree with this quote?

Not so agreed.  I think lovers can be even different instead of the same soul. 

Let's start with the basics. How do we put these big ideas into words? 

Love is usually used in intimate relationship, while the word of "connection" refers to a bigger thing, like academy connection, profession connection and etc.

In your own words, what is "true love"? Is it a feeling, an action, or a choice?

Hard to say, because it's hard to define what true love is.

What is the difference between love and connection? Can you have one without the other?

Usually connection is based on interests. However, when we say love, we usually expect that love is free from interests. At least, we seldom talk about interests in love between parents and children, between a man and his partner and between a man and his homeland.
