Jean-Paul Sartre said this quote

“ Let us see what words can do. Will you understand me, for a start, if I tell you that I have never known what I am? My vices, my virtues, are under my nose, but I can’t see them, nor stand far enough back to view myself as a whole. I seem to be a sort of flabby mass in which words are engulfed; no sooner do I name myself than what is named is merged in him who names, and one gets no farther. I have often wanted to hate myself and, as you know, had good reasons for so doing. But my attempted hatred of myself was absorbed into my insubstantiality and was nothing but a recollection. I could not love myself either, I am sure, though I have never tried to. But I was eternally compelled to be myself; I was my own burden, but never burdensome enough, Mathieu. For one instant, on that June evening when I elected to confess to you, I thought I had encountered myself in your bewildered eyes.You saw me, in your eyes I was solid and predictable; my acts and moods were the actual consequences of a definite entity. And through me you knew that entity. I described it to you in my words, I revealed to you facts unknown to you, which had helped you to visualize it. And yet you saw it, I merely saw you seeing it. For one instant you were the heaven-sent mediator between me and myself, you perceived that compact and solid entity which I was and wanted to be in just as simple and ordinary a way as I perceived you. For, after all, I exist, I am, though I have no sense of being; and it is an exquisite torment to discover in oneself such utterly unfounded certainty, such unsubstantiated pride. I then understood that one could not reach oneself except through another’s judgment, another’s hatred. And also through another’s love perhaps; but there is here no question of that. For this revelation I am not ungrateful to you. I do not know how you would describe our present relations. Not goodwill, nor wholly hatred. Put it that there is a corpse between us. My corpse. ”
