Except our own thoughts, there is nothing absolutely in our power.

My third maxim was to try always to master myself rather than fortune and change my desires rather than changing how things stand in the world.

My third maxim was to endeavour always to conquer myself rather than fortune, and change my desires rather than the order of the world, and in general, accustom myself to the persuasion that, except our own thoughts, there is nothing absolutely in our power;

My principle has ever been to attempt to overcome myself rather than fortune and to change my desires rather than the natural order.

Always to seek to conquer myself rather than fortune, to change my desires rather than the order of the world, and generally to believe that nothing except our thoughts is wholly under our control, so that after we have done our best in external matters, what remains to be done is absolutely impossible, at least as far as we are concerned.

Así como la existencia del yo ha sido, en el cogito, establecida por una intuición intelectual, también la existencia de Dios queda establecida en el argumento ontológico por medio de una deducción (que para Descartes es una serie de intuiciones intelectuales). La metafísica del cartesianismo y filosofías subsiguientes tienden, por modo inevitable, a demostrar las existencias, mediante actos intelectuales subjetivos.

I doubt;
Therefore, I think
Therefore, I am.

I see;
I take in the colours around me.
The patterns, the lights, the rainbows.
I see the night and the stars that glow.

I dream;
Therefore, I think.
Therefore, I am.

I smell;
The perfumes, the roses.
The stench, the rotten and the putrid.
The aromas and delicacies;
Cooking.

I inhale;
The green, the forest, the trees.
Therefore, I think.
Therefore, I am.

I hear;
The noises. The people, the cheer.
The wails, the screams, the tears.
The rejoicing.
The laughter, and happiness.

I listen;
Therefore, I think.
Therefore, I am.

I taste;
The sweetness, the fire.
The treats, and savoury delights.
The burnt, the spoilt and the tasteless.
The sourness and the bitterness.

I eat;
Therefore, I think.
Therefore, I am.

I speak;
Short messages. Long speeches.
Quiet whispers. Bellowing noises.

I scream;
Therefore, I think,
Therefore, I am.

I feel;
The despair.
The anguish, the fear.
The pricks, the cuts, the injuries.
The joy. The pride. The seething.
The envy, greed, and jealousy.
The cold, the heat and the shivering.
The pain, the sickness, the ageing.

I die;
Therefore, I lived.
Therefore, I was.

And in this it is not likely that all are mistaken the conviction is rather to be held as testifying that the power of judging aright and of distinguishing truth from error, which is properly what is called good sense or reason, is by nature equal in all men; and that the diversity of our opinions, consequently, does not arise from some being endowed with a larger share of reason than others, but solely from this, that we conduct our thoughts along different ways, and do not fix our attention on the same objects. For to be possessed of a vigorous mind is not enough; the prime requisite is rightly to apply it. The greatest minds, as they are capable of the highest excellences, are open likewise to the greatest aberrations; and those who travel very slowly may yet make far greater progress, provided they keep always to the straight road, than those who, while they run, forsake it.
