“Knowledge is the food of the soul; and we must take care, my friend, that the Sophist does not deceive us when he praises what he sells, like the dealers wholesale or retail who sell the food of the body; for they praise indiscriminately all their goods, without knowing what are really beneficial or hurtful.”

— Plato , book Protagoras

“Saying that what we call our “selves” consist only of our bodies and that reason, soul, and love arise only from the body, is like saying that what we call our body is equivalent to the food that feeds the body. It is true that my body is only made up of digested food and that my body would not exist without food, but my body is not the same as food. Food is what the body needs for life, but it is not the body itself. The same thing is true of my soul. It is true that without my body there would not be that which I call my soul, but my soul is not my body. The soul may need the body, but the body is not the soul.”

“He who does not know what the world is, does not know where he is. And he who does not know for what purpose the world exists, does not know who he is, nor what the world is. But he who has failed in any one of these things could not even say for what purpose he exists himself. What then dost thou think of him who [avoids or] seeks the praise of those who applaud, of men who know not either where they are or who they are?”

Marcus Aurelius book Meditations

He that knows not what the world is, knows not where he is himself. He that knows not for what he was made, knows not what he is nor what the world is.
VIII, 52

“And the same applies to the spouse. You know you love them, but you need to say it again and again. Like we got to the food, moments ago, and you need to say: "This food is – mashallah – it's really, really great". Even if the salt is a little bit more. Because sometimes, as I was saying, she spent so much time bringing it in front of us – and we are worried about how it's smelling, number one, and number two is we say, as we taste it, "The salt is too much, no?" What are you talking about? She just looks at you and her face flops. «I've been at it for three hours here, four hours I've been busy with this for so many months…» And what does she even say? "Next time I'll try a bit harder" – that's if she's a good woman; if not, she will say: "Never gonna cook this again!" It's typical. And if you have someone who is very witty: "The next time there's salt to be put in, I'll call you to put it." So we need to praise the cooking of our wives, we need to praise their dress code, especially… For example, I can let you know something that has worked, for some people. When you find some women, you know, they don't like to dress appropriately, so the husband sometimes wants to tell them something. There're two, three ways of doing it. You can either say, "This is very bad, I don't want you to wear this." And, you know, you might have a response. But if you want a response from the heart, what you do is, you tell them: "The other dress looked much better than this." You see, so you are praising one thing, and that praise is not there when the other thing is there. So, you have told them, in a way, that «this is what I really love». And go beyond the limits in praise – that's your wife, don't worry, you can say whatever you want, mashallah, in terms of goodness. Like the food, when you eat, even if it is a little bit this way or that way, just praise it, mashallah. See what it is. Praise the effort, at least. Let me tell you what has happened once. They say the imam in the mosque had said: "You need to praise the cooking of your wife". Just like I said now. So the man went home, and he had this meal, and he was looking at it, and looking at his wife, and smiling, all happy, mashallah, excited and everything. And when he finishes, he says: "Oh! It was awesome!" And the wife says, "What? I've been cooking for you for 21 years, you never said that! Today, when the food came from the neighbor, you want to say it was awesome?"”

“The goal of mankind is knowledge.... Now this knowledge is inherent in man. No knowledge comes from outside: it is all inside. What we say a man "knows," should, in strict psychological language, be what he "discovers" or "unveils"; what man "learns" is really what he discovers by taking the cover off his own soul, which is a mine of infinite knowledge.”
