How to Improve your Mind

How to Improve your Mind by Baruch Spinoza

Spinoza seeks a real good capable of giving the mind continuous and supreme happiness, after judging the usual aims of social life—Riches, Fame, and Pleasures of Sense—to be vain when pursued as final ends. Sensual pleasure enslaves the mind and brings melancholy after gratification; wealth and reputation intensify desire, expose their pursuers to danger and sadness, and make people conform their lives to popular opinion. Such goods become harmful when loved as perishable ends, but can serve the higher aim when restrained and used as means. The true good is the acquisition of a more stable human character: knowledge of the union between the mind and the whole of nature. The highest good includes helping others attain this understanding. Moral Philosophy, Education, Medicine, and Mechanics are valuable insofar as they aid this purpose, but the first necessity is to improve and purify the understanding. Meanwhile, one should speak intelligibly to the multitude and follow harmless customs, take pleasure only as health requires, and seek only enough money and goods to preserve life and health. The work distinguishes four modes of perception: hearsay; unclassified experience; inference from effects, general propositions, or inadequate causes; and knowledge through a thing’s essence or proximate cause. Hearsay and mere experience are uncertain and do not reveal essences. Inferential knowledge can yield safe conclusions but does not by itself achieve perfection. The fourth mode alone grasps adequate essences without error and must guide inquiry. Method does not require an endless search for a prior method. Just as people gradually make better material tools from simple natural instruments, the intellect uses its native strength to create intellectual instruments, gaining greater power through its own operations. A true idea is distinct from its object, can be understood in itself, and supplies certainty without requiring an external sign. Certainty is the mind’s possession of the subjective essence of a thing. Method is therefore reflective knowledge, or the idea of an idea: it directs the mind according to a given true idea, distinguishes truth from other perceptions, and furnishes rules for inquiry. The mind should increase its knowledge of nature, since understanding more objects improves self-knowledge, reveals the order of nature, and helps avoid useless effort. Ideas should correspond to the connections among real things, and all ideas should ultimately be deduced from the idea representing the origin and source of the whole of nature. The most perfect method would proceed from the idea of the absolutely perfect being. Fictitious ideas concern possible things whose necessity or impossibility is unknown. Fiction disappears where a thing’s nature is clearly understood, for clear knowledge prevents one from imagining contradictions or arbitrary absurdities. Fictions arise from confused and partial knowledge, especially when diverse images and memories are blended without distinct understanding. False ideas differ from fictions because they involve assent: one treats a confused representation as if it came from an external object. Clear and distinct ideas cannot be false; falsity consists in affirming of a thing something not contained in the conception of it. Doubt arises not from an isolated idea but from another idea that is insufficiently clear and distinct. It is removed through ordered investigation and adequate knowledge. Imagination, memory, words, and abstraction are major sources of error. Memory depends on sensations and duration, while the understanding itself contains neither memory nor forgetfulness. Words follow popular habit and imagination rather than intellectual reality, so they can lead the mind to mistake verbal forms for the nature of things. The second part of method requires conceiving each thing through its essence if it is self-existent, or through its proximate cause if it is caused. Inquiry must avoid drawing conclusions about real things from abstractions or universal axioms alone. Good definitions explain an object’s inmost essence rather than merely one of its properties; for created things, they include the proximate cause and permit the deduction of properties. Knowledge should proceed through fixed and eternal things and their laws, rather than through the innumerable mutable particulars whose changing circumstances do not reveal their essence. The concluding discussion enumerates properties of the understanding. It possesses certainty; forms some ideas directly and others from prior ideas; conceives infinity, positive ideas, eternity, and clear necessity; can determine ideas in many ways; and is more perfect in proportion to the perfection expressed in its ideas. False and fictitious ideas reveal no positive essence of thought, because they arise only from defective knowledge; the nature and power of understanding must be known through its positive properties.

First lines

AFTER experience had taught me that all the usual surroundings of social life are vain and futile; seeing that none of the objects of my fears contained in themselves anything either good or bad, except in so far as the mind is affected by them, I finally resolved to inquire whether there might be some real good having power to communicate itself, which would affect the mind singly, to the exclusion of all else: whether, in fact, there might be anything of which the discovery and attainment would enable me to enjoy continuous, supreme, and unending happiness. I say "I finally resolved," for at first sight it seemed unwise willingly to lose hold on what was sure for the sake of something then uncertain. I could see the benefits which are acquired through fame and riches, and that I should be obliged to abandon the quest of such objects, if I seriously devoted myself to the search for something different and new. I perceived that if true happiness chanced to be placed in the former I should necessarily miss it; while if, on the other hand, it were not so placed, and I gave them my whole attention, I should equally fail.
