Alberto Caeiro said this quote

I don’t have a philosophy: I have senses...If I talk about Nature, it’s not because I know what it is,But because I love it, and that’s why I love it,Because when you love you never know what you love,Or why you love, or what love is.Loving is eternal innocence,And the only innocence is not thinking.

~ Alberto Caeiro

It’s an already inside outside,The philosophers say it’s the soulBut it’s not the soul: it’s the animal or the man itselfIn its way of existing.

~ Alberto Caeiro

She’s a manner of speaking.Even the flowers don’t come back, or the green leaves.There are new flowers, new green leaves.There are other beautiful days.Nothing comes back, nothing repeats itself, because everything is real.

~ Alberto Caeiro

To love is to think.And I almost forget to feel only from thinking about her.I don’t know what I want at all, even from her, and I don’t think about anything but her.I have a great animated distraction.When I want to meet her,I almost feel like not meeting her,So I don’t have to leave her afterwards.And I prefer thinking about her, because it’s like I’m afraid of her.I don’t know what I want at all, and I don’t want to know what I want. All I want to do is think about her.I’m asking nothing of nobody, not even her, except to think.

~ Alberto Caeiro
