Is it true that we never really know another person, what we seem to know is only our perceptions of another?

very true....some time we see other as we want him/her to be and which becomes the reason of many disappointments .

The perception of others we have consists of how that person is projecting him self, how we view the other person ,what are the circumstances or conditions under which are made to assess the person and many other factors.Our perception may change from time to time but remains the basic tool to assess anybody.

Yes very true. It is not only our perceptions of that person but also the circumstances and situations at that particular point of time when we tend to form our opinions about the person.

In essence, yes. Because you only see what the other person wants you to see. Most people portray themselves the way that they want others to perceive them.

For example, if I am alone and I stub my toe, I might let out an explicit word. But if I am in front of a stranger, then I am more likely to say "Ouch!" because I don't want that stranger to think that I have a potty-mouth...but in reality, sometimes I do have a potty-mouth...but only in front of the people that I don't mind knowing that about me.

But on the other side of the fence, our own personal biases and morals skew the image that we get of another. Because we always throw in our own experiences and beliefs when judging others.

Whatever there is in our mind,we perceive the thing in that way.e.g if someone says about another lady who is very beautiful and later on you meet the lady, you feel that this woman is not that beautiful that is the perception.

Very true,,

people judge others by mixing their own perceptions,biases, insecurities.

Absolutely true.........

Very often, we tend to perceive another person, the way we want to see him/ her.

In this context, I'd refer to the 'Johari window', which gives 4 facets of ones personality in terms of 'known/ unknown to self' and 'known/ unknown to others'. A study of the 'window' helps people to develop self awareness and to better understand their interpersonal communication and relationships.

YES

so true

This kind of deep sh*t will keep me thinking for days

Everytime I hear quotes like these I feel my perception is completely tainted

Har adami me baste hain kai adami, juraurat hai bar bar dekna ki.

Yes the whole world is a stage and we all are actors. So people see what we want to show to others.

Yes it is true to some extent when we get married to person and we presume that he is good, loyal and trust worthy etc.But when we begins to live life with them it is quite opposite what we perceive first.
